Computer vision is one of the important research based field which deals with how computers can be made to gain high-level understanding from digital images or videos. Computer vision projects include methods for acquiring, processing, analysing and understanding digital images. Computer Vision engage in taking out of high-dimensional data from the
Existent world in order to produce numerical or symbolic information for e.g., in the forms of decisions. The images understanding can be seen as the compassionate of symbolic information from image data by using many different models established with the help of geometry, physics, statistics, and learning theories. The research based discipline of computer vision is concerned with the theory behind artificial systems that extract information from images. The image data can be taken in many different forms, such as video sequences, views from multiple cameras, or multi-dimensional data from a medical scanner. The computer vision includes such as scene reconstruction, event detection, video tracking, object recognition, 3D pose estimation, learning, and indexing and image restoration.
