What is Computer Vision?
Computer Vision is an interdisciplinary field that deals with how computers can gain understanding from images and videos. In simple terms, it involves teaching computers to identify and interpret visual data from the world around us. This field is characterized by the use of algorithms and mathematical models to extract information from images, which is then used to make decisions or predictions.
The role of Artificial Intelligence
Artificial intelligence (AI) plays a crucial role in the field of computer vision. AI algorithms are used to train computers to recognize and interpret visual data. This is done through a process called deep learning, which involves training a neural network to recognize patterns and make decisions based on those patterns. The most popular deep learning framework used in computer vision is PyTorch.
