Description

Figure analysis device based on computer intelligence vision

Technical Field

The invention relates to the technical field of computer vision, in particular to a graph analysis device based on computer intelligent vision.

Background

With the rapid development of deep learning, computer vision has become the most important technology in the field of artificial intelligence. Computer vision is considered as an important branch of artificial intelligence, which equates to the door to artificial intelligence. Computer vision refers to machine vision that uses a camera and a computer to simulate human vision to identify, track, measure and the like a target, and further performs graphic processing through identification and analysis, so that the computer processing becomes an image more suitable for human eye observation or transmitted to an instrument for detection. This technology plays a great role in creating artificial intelligence systems that can obtain "information" from images or multidimensional data.

In short, the perception, identification and understanding of three-dimensional scenes of an objective world are realized by utilizing a computer to realize human vision. Machines are capable of performing tasks and specific functions requiring human intelligence, relying in large part on computer vision in computer systems, such as visual perception, image recognition, face recognition, body recognition, object localization, and the like. In recent years, the global computer vision market is rapidly rising in order to make computers more human-like, recognize objects, deeply learn, and rapidly develop computer vision technical methods and applications. With the warming of the artificial intelligence industry, the computer vision industry is also expanding at an accelerated pace.
