Digital image processing is the use of computer algorithms to perform image processing on digital images. It allows a much more comprehensive range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing. Computer vision is an interdisciplinary field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to automate tasks that the human visual system can do. Computer vision tasks include methods for acquiring, processing, analyzing, and understanding digital images.

The research in this area is focused on image processing and computer vision, vision and machine learning, mathematical modeling and analysis of images, low-level image processing algorithms, medical image analysis and processing, features extraction and selection, pattern recognition and classification, video surveillance, and video processing.
