Computer Vision technology in a nutshell
Computer Vision is a transformative branch of artificial intelligence that allows machines to interpret and process visual data, much like the human eye. At its core, Computer Vision involves algorithms that let computers receive and analyse visual information from digital images or videos, then make decisions or perform actions based on that information.
How Computer Vision systems works
Computer Vision systems capture visual data through cameras or sensors, which is then processed using algorithms and machine learning models. These models are trained on vast datasets of images, enabling them to recognize patterns, shapes, and objects by matching what they see to similar things in the training dataset. The process involves several steps – from image acquisition and processing to feature extraction and decision-making.
Most common Computer Vision Applications:
- Image Recognition: Identifying objects, people, or other targets within an image.
- Object Detection: Locating and identifying multiple objects within an image or video.
- Pattern Recognition: Recognizing complex patterns and regularities in data.
- Segmentation: Partitioning an image or video into multiple segments or objects.
- Machine Learning and Deep Learning: Utilising neural networks to improve the accuracy and efficiency of image analysis.
