Definition of computer vision: Computer vision is not only an engineering field, but also an important and challenging research field in the scientific field. Computer vision is a comprehensive subject, which attracts researchers from various disciplines to participate in its research. These subjects include computer science and engineering, signal processing, physics, applied mathematics and statistics, neurophysiology and cognitive science.
Principle: Computer vision uses various imaging systems instead of visual organs as input sensitive means, and computers instead of brains 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 people, and have the ability to adapt to the environment independently. It takes a long time to achieve the goal. Therefore, the mid-term goal of people's efforts is to establish a visual system to accomplish certain tasks according to a certain degree of intelligence of visual sensitivity and feedback.
Medical computer vision
Application: The most prominent application fields are medical computer vision and medical image processing. For the purpose of medical diagnosis of patients, the feature information of this region is extracted from the image data. The application of computer vision in the medical field also includes enhancing people's perception, such as ultrasonic images or X-ray images, to reduce the influence of noise on images.
