Weak and small target change intelligent image detection method and device

Abstract

The invention provides a weak and small target change intelligent image detection method comprising the following steps that step one: foreground and background segmentation: step 11: the adaptive threshold of the frame of image is obtained; step 12: foreground and background segmentation is performed on the image through combination of the image segmentation algorithm so as to obtain an ideal binary segmentation image; step two: motion detection: step 21: local normalization is performed on the acquired image; step 22: block matching motion estimation is performed on the binary segmentation image, and two motion detection binary images are combined to obtain the motion result image; and step three: target locating: less than 3 motion points within eight neighborhoods are filtered firstly;then four points are expanded in the four neighborhoods of the rest target points and the expanded image is obtained; then each independent target block of the expanded image is extracted and the blocks of which the area is greater than 15 act as the real target blocks; and finally all the detected motion targets are marked. The invention also discloses a weak and small target change intelligentimage detection device.

Description

technical field [0001] The invention belongs to the technical field of image technology processing, in particular to an intelligent image detection method and device for weak and small target changes. Background technique [0002] Computers have been widely used in all walks of life, and they are more accurate and faster than humans in handling repetitive, large-scale, and computationally intensive tasks. At the same time, people can also use computers to complete some more intelligent tasks, such as image recognition, speech recognition, data mining, natural language processing, etc. Research in the field of artificial intelligence attempts to allow computers to perceive and process information like humans, while computer vision aims to give computers human visual capabilities so that computers can automatically understand visual information. According to the analysis data of relevant researchers from the Harvard Business School in the United States, the human brain receiv...
