What is Computer Vision?
Computer Vision is a field of artificial intelligence that enables machines to interpret and understand visual data from the world, such as images and videos. By mimicking human vision, computer vision systems can identify objects, recognize faces, analyze scenes, and extract meaningful information to make decisions or automate tasks.
How Does Computer Vision Work?
Computer vision systems process visual data through several steps:
- Image Acquisition: Capturing images or video from cameras or sensors.
- Preprocessing: Enhancing image quality and removing noise.
- Feature Extraction: Identifying important patterns like edges, shapes, or textures.
- Object Detection and Recognition: Locating and classifying objects within images.
- Post-processing: Interpreting results and integrating with applications.
Popular Techniques and Models in Computer Vision
- Convolutional Neural Networks (CNNs): Deep learning models specialized for image data.
- Image Segmentation: Dividing an image into meaningful parts.
- Object Detection Algorithms: Such as YOLO, SSD, and Faster R-CNN.
- Facial Recognition: Identifying or verifying faces in images.
- Optical Character Recognition (OCR): Extracting text from images.
