What is Computer Vision?

Computer vision enables machines to interpret and understand visual information from the world. Using machine learning (ML) and deep learning (DL) algorithms, computer vision systems analyze and process images and videos to extract meaningful data, making it possible for applications such as autonomous vehicles, medical imaging, and surveillance systems to operate effectively.

Underlying Technology of Computer Vision

Computer vision relies on several core technologies to function effectively. These include:

Image Processing Techniques

Thresholding: Converts grayscale images into binary images based on a threshold value, separating objects from the background.

Edge Detection: Identifies boundaries within images using algorithms like the Canny edge detector, crucial for understanding shapes and positions.

Machine Learning and Deep Learning

Convolutional Neural Networks (CNNs): Break images into pixels, apply convolutions, and make predictions about what the system sees. CNNs are particularly effective for image recognition and classification tasks.

Recurrent Neural Networks (RNNs): Used for video applications, RNNs understand the sequence of frames and their relationships, making them suitable for tasks like object tracking in videos.

Advanced Models

ResNet-50: A deep learning model with 50 layers, ResNet-50 uses residual blocks to overcome the vanishing gradient problem, enabling it to learn complex features and perform high-accuracy image classification.

YOLO (You Only Look Once): A real-time object detection model that processes images quickly, identifying objects in a single pass through the network. YOLO is widely used in applications requiring speed, such as autonomous driving and surveillance.

Vision Transformers (ViTs)

Transformer Architecture: Originally designed for natural language processing, this model applies to images by dividing them into patches, embedding them, and processing them through a transformer encoder.

Key Features: Includes patch-based image processing, positional embeddings, and multi-head attention mechanisms, making ViTs efficient and accurate for image classification and object detection.
