Computer Vision in Industry

What is Computer Vision?

Computer Vision (CV) is an area of artificial intelligence that gives computers the ability to extract meaningful information from digital images.  Using advanced technologies such as machine learning and deep neural networks, machines are enabled to mimic the human eye and brain.  The main purpose of computer vision is to analyze data in digital images to identify objects, analyze movements, interpret complex scenes, improve images, and create 3D models from 2D images.  This technology also has a wide range of uses in the industrial field.  Quality control, inspection, automation, safety systems, robotic/machine vision, autonomous vehicles are involved in many application areas, such as efficiency improvement, smart factories and integrated systems.  Computer vision plays a critical role in the industry to improve quality, speed up production processes, ensure safety and optimize operations.  The effective use of this technology makes significant contributions to companies’ competitiveness and lower costs.

The Relationship Between Computer Vision and Image Processing

Although the fields of computer vision and image processing share similar techniques that involve working on images, they are separated by different purposes and approaches.  Both fields work on digital image data and focus on the analysis and processing of images using mathematical, statistical methods.  For example, techniques such as filtering, conversions, and feature extraction are widely used in both computer vision and image processing.  However, image processing often involves higher-level tasks such as correcting, refining, compressing, or converting raw images, while computer vision involves extracting meaningful information from images, recognizing objects, and understanding scenes.   In image processing, the result is usually a processed or improved image, while in computer vision, the result is the information extracted from the image and the use of that information to make certain decisions or perform actions.  Computer vision usually requires a data set for artificial intelligence training, while image processing systems do not require a pre-trained model.

Computer Vision Operating Principle

Computer vision applications use sensing devices, artificial intelligence, machine learning and deep learning to mimic the human vision system.  This process starts with acquiring images with devices such as digital cameras.  The resulting images are represented as pixel matrices, and raw images are often subjected to preliminary image processing steps such as noise removal, contrast enhancement, and size change.  This makes the images suitable for further analysis.  Feature extraction and detection are then performed from the images.  At this stage, the properties of objects and objects in the image are detected and transmitted to machine learning and deep learning models.  Finally, computers use this information to perform many tasks, such as object recognition or classification, and make decisions based on the application.   For example, a machine vision system running on a production line performs quality control of products.  This system detects defects on the surface of products, measures their size and checks for color deviations.  As a result of detected defects, the system automatically separates defective products and ensures that only products that comply with quality standards can progress on the production line.

Computer Vision in Manufacturing and industry

Computer vision simplifies product processing with technology support from manufacturers.  Manufacturers, product packaging, inspection, quality control, design, they can identify images and videos through previously trained data for use in areas such as product sorting and process automation.  Computer vision, a component of the digital transformation ecosystem, has the potential to offer companies a competitive advantage.  Manufacturers who want to be at the forefront of change in the sector are particularly keen to adopt this technology.

    • ○ Danger Zone and Access Control:
      • ◾ In industrial facilities, certain areas may be hazardous and should be accessible only to authorized personnel.  Computer vision can prevent security breaches by detecting intrusion in these areas.
      • ◾ For example, in a chemical factory, when an unauthorized person is found to have entered the hazardous materials area, the alarm system is activated.
    • ○ Machine and Equipment Safety:
      • ◾ Computer vision systems can monitor whether industrial machines and equipment are operating safely.  When abnormal vibrations, overheating or misuse are detected, these systems can automatically stop machines or notify the maintenance team.
      • ◾ For example, on a production line, when a possible sign of malfunction is detected on the machines, the computer vision system stops the process and alerts the operators.
    • ○ Fire and Smoke Detection:
      • ◾ Computer vision is used for fire or smoke detection in industrial facilities.  These systems, in addition to fire detectors, can detect smoke in the early stages or signs of fire.

Computer Vision General tasks

  • Image Classification: The task of assigning an image to a specific class is to categorize products and separate defective products on automated production lines.
  • Object Detection: The task of identifying and locating certain objects in the image, allowing the detection of intrusion on security cameras or the detection of missing components on the production line.  It can also detect certain objects in 3D, and the 3D model found can be used in a variety of areas.
  • Segmentation is the process of assigning each pixel in an image to a class and is used to detect faulty painting or assembly problems on the production line.
  • Image production: The task of creating new images based on a specific input and is used to create new designs during the product design and prototyping phases.
  • Image Super Resolution: The process of making a low-resolution image high-resolution, used to improve low-resolution images obtained from security cameras.

Key technologies used

Many technologies and methods have been developed to perform these basic computer vision tasks.

  • ● Convolutional Neural Networks (CNNs):
    • ○ CNNs are deep learning models used to process and make sense of image data. It is widely used in tasks such as image classification and object detection.  State-of-the-art deep learning models like YOLO are built on CNN architecture. CNNs are used extensively in image processing and deep learning for many reasons.
      • ◾ CNN’s are great at capturing the spatial hierarchy in images. Convolution layers form a hierarchy from low-level properties (for example, edges) to high-level properties (for example, objects).  In this way, important features in images can be better defined and analyzed.
      • ◾ Techniques such as max-pooling, batch-normalization, and dropout ensure that CNNs are robust against factors such as displacement and scalability. This helps the model resist the object's position and size in the image.
      • ◾ CNNs learn certain features over and over again by sliding over the image using filters (kernels). This feature sharing reduces the number of parameters and makes the model more efficient.  This makes it possible to train deeper networks with fewer parameters.
      • ◾ CNN specializes in capturing the local correlations of images. Each convolution filter operates in a specific receptive field so that it can learn important features regardless of the position of objects.
      • ◾ CNNs eliminate the need to manually extract features from images. Instead, the model automatically learns the most meaningful features during the training process.  This provides a huge advantage in tasks such as image recognition, object detection and segmentation.
      • ◾ CNNs perform exceptionally well on image processing and computer vision tasks. It is one of the most popular among deep learning models and usually provides higher accuracy than other methods.
      • ◾ CNNs allow re-use of pre-trained models. Thanks to transfer learning, retraining a model for another task requires much less data and shorter training time.
      • ◾ When CNNs are trained in large datasets, their generalization capabilities are quite powerful. This ensures that the model also performs well on new data outside of the training data.

               CNN’s visualization is as below:

  • ● R-CNN, Fast R-CNN ve Faster R-CNN:

Object detection is a technique used to determine the location and classes of certain objects in an image or video.  R-CNN (region-based Convolutional neural Networks) and its improved versions, fast R-CNN and faster R-CNN, are among the groundbreaking methods in this field.  These models have been developed to improve the speed and accuracy of object detection.

  1. 1. R-CNN (Region-based Convolutional Neural Networks): R-CNN is one of the first region-based approaches to object detection.  R-CNN’s working principle consists of 3 steps: Zone Recommendation, Convolutional neural Network and Classification, and Bbox Regression.  Since CNN needs to run repeatedly for each zone recommendation, this approach requires a lot of computation, which in turn extends the processing time.
  2. 2. Fast R-CNN: Fast R-CNN was developed to solve R-CNN's slowness problem.  The biggest innovation of this model is that the entire image is rendered in a single CNN transition.  Then, faster and more efficient actions are made on the district recommendations.  Unlike R-CNN, fast R-CNN feeds the entire image to CNN at once and maps out the feature.  This eliminates the need to run CNN separately for each region recommendation.
  3. 3. Faster R-CNN: Faster R-CNN has gone a big step further in object detection, further optimizing the region recommendation process.  This model integrated the region recommendation phase into an end-to-end structure, resulting in a great improvement in speed and accuracy.  Faster R-CNN’s most important innovation is the introduction of a network called RPN.  RPN suggests potential object regions at each location using a floating window on the image.  This network is a purely convective network that quickly generates region recommendations.

The evolution from R-CNN to faster R-CNN shows how speed and accuracy can be optimized in object detection.  These models are used in many computer vision applications today and have achieved significant success, especially in tasks such as object detection and classification.

  • ● YOLO (You Only Look Once):

YOLO is known as a groundbreaking model in the field of object detection and has a wide range of uses in computer vision applications.  The biggest feature of YOLO is that it can perform object detection operations very quickly and efficiently in real time.  Various versions of YOLO have been developed, and with each new version, performance and accuracy are further enhanced.  YOLO processes an image in a single pass.  During this transition, the image is divided into a certain number of cells (grid) and each cell decides whether it contains objects.  If an object exists, this cell predicts the class and position of the object.  The grid-based approach divides the image into a grid of SxS dimensions.  Each grid cell suggests a certain number of bounding boxes and determines which class of objects these boxes belong to.  You can see an example of this in the image below.

YOLO is a revolutionary model for object detection.  Due to its speed and accuracy, it is preferred in many real-time applications.  Each new version further enhances the power of YOLO, making it an indispensable tool in the computer vision.  YOLO’s core principles and advantages make it important both in the world of research and in industrial applications.

  • ● Generative Adversarial Networks (GANs):

Generative adversarial Networks (GANs) is a very popular and effective type of artificial intelligence model.  Invented by Ian Goodfellow and colleagues in 2014, it revolutionized the field of image creation, data augmentation, and data imitation.  GANS are made up of two main components: A   generator (manufacturer) and a discriminator (separator).  The training of GANS takes place when these two models compete with each other like a game.  While the manufacturer tries to produce data that is good enough to fool the parser, the parser tries to catch this fake data.  This process continues until the manufacturer is able to generate much more realistic data.  The relationship between these two models is as follows:

GANS offer a revolutionary innovation in the field of deep learning and artificial intelligence.  GANS, which have opened new doors in many areas such as image creation, data augmentation and so on, can form the basis for many future applications.   For example, with SRGAN, a low-resolution image can be moved to a higher resolution.

  • ● U-Net:

U-Net is a neural network architecture that is particularly used in biomedical image processing and is also effective in other image segmentation tasks. Developed by Olaf Ronneberger and his team in 2015, this architecture is distinguished by its ability to achieve high accuracy results with limited training data.  U-Net takes its name from its symmetrical structure, which resembles the letter "U", and consists of two main parts: The encoder and the decoder.  The encoder converts the input image into a series of increasingly smaller feature maps, while the solver uses these maps to produce a pixel-by-pixel segmentation mask at the original size of the input image.  The symmetrical structure of the U-Net is formed by the combination of both stages.  The architecture from which U-Net gets its name is as follows:

U-Net is a revolutionary architecture in the field of image segmentation.  This network structure, which has proven itself especially in the biomedical field, is also successfully applied in other image processing tasks.  Thanks to its skip connections and fully convunctional structure, it can perform well even in low data environments.  One of the most important articles today, segment anything, developed by Facebook, was inspired by the U-Net architecture and Transformer technology.

  • ● Feature Pyramid Network (FPN), is a feature extractor that takes a single-scale image as input and produces feature maps at multiple levels, proportional sizes.  This process is carried out in a purely convolutional manner and is independent of the backbone convolutional architectures used.  Therefore, it functions as a general solution that can be used in tasks such as object detection to create feature pyramids within deep convulsive networks.
  • ● Vision Transformer (ViT), is a model used for image classification and uses a Transformer-like architecture on parts of the image.  An image is divided into fixed-size pieces;  Each part is embedded linearly, position embeds are added, and the resulting vector array is fed into a standard Transformer encoder.  To classify, an additional learnable "classification token" standard is applied at the end of the sequence.
  • ● Residual Networks (ResNets), now learn functions by reference to layer entries, rather than learning non-referenced functions.  Instead of waiting for a few layers to learn the basic map directly desired, residual networks allow these layers to learn a residual map.  Resnets form a network by adding layers of residual blocks, each one of which is superimposed.  For example, a ResNet-50 consists of fifty layers using these blocks.

In addition to these technologies, Mask R-CNN, DeepLab for semantic segmentation;  FaceNet, DeepFace for facial recognition, OpenPose and DensePose for exposure prediction, neural Radiance fields and Gaussian Splatting methods for 3D modeling are also frequently used as important technologies.
