Computer vision direction includes: 1. image classification; 2. object detection; 3. image segmentation; 4. object tracking; 5. image filtering and noise reduction; 6. image enhancement; 7. Iterative reconstruction; 8. image retrieval.

Definition of Computer Vision: Computer vision is not only an engineering field, but also a challenging and important research field in the field of science. Computer vision is a comprehensive discipline that has attracted researchers from various disciplines to participate in its research. These include computer science and engineering, signal processing, physics, Applied mathematics and statistics, neurophysiology and Cognitive science.

Principle: Computer vision is the use of various imaging systems to replace visual organs as input sensitive means, and the computer replaces the brain to complete processing and interpretation. The ultimate research goal of computer vision is to enable computers to observe and understand the world through vision like humans, and to have the ability to autonomously adapt to the environment. A goal that requires long-term effort to achieve. Therefore, the mid-term goal of people's efforts is to establish a visual system that can complete certain tasks based on a certain degree of intelligence in visual sensitivity and feedback.
