Embodiment 1

[0033] At the end of 2012, several consecutive cases of robbing citizens of ATM withdrawals occurred in a certain city in Fujian, and the social impact was bad. From the bank's surveillance video, a clear frontal photo of the suspected target was obtained. But where did the suspect come from? To this end, the police collected a large amount of surveillance video data from the surrounding area, hoping to find out. At that time, the method of video retrieval was also used to retrieve the suspect according to the color of the suspect's clothes and the possible direction of movement. The needle was found in a haystack to find a video of the suspect coming out of the Internet cafe. Finally, the suspect was captured using online records.

[0034] What happens if the video retrieval method based on sample images of this embodiment is used? See figure 1 Shown:

[0035] Step 1) Sample image import

[0036] Import the sample picture of the subject matter to be retrieved, that is, import t...

Abstract

The invention discloses a video retrieval method based on a sample image, and the video retrieval method is used for achieving searching of images through an image. The video retrieval method based on the sample image comprises the following steps that 1), a sample image is imported; 2), the sample image is analyzed in a structured mode; 3), sample image information is put into a library; 4), an original video is imported; 5), video transcoding is conducted; 6), video structured analysis is conducted; 7), video information is put in a library; 8), the sample image is compared with the original video information; 9), the result is shown. According to the video retrieval method based on the sample image, the video retrieval technology enables complex semantic description to be replaced by the vivid sample image, and the effect of searching the images through an image in huge amounts of videos is achieved.

Description

Technical field [0001] The invention belongs to the technical field of video processing, and relates to a video analysis method, in particular to a video retrieval method based on sample images. Background technique [0002] With the advancement of the Skynet project, a huge amount of surveillance video has been produced, and video detection technology has become one of the most commonly used detection technologies for public security. However, how to access massive videos has become a bottleneck in the in-depth application of video resources. [0003] At present, the public security has begun to improve the efficiency of video viewing through video retrieval technology. The retrieval method is only semantic retrieval, for example, searching for "a silver van away from the direction of the screen" in the video. However, many features are difficult to describe in semantics, such as facial features and striped clothes. If you can use picture samples as input, it is undoubtedly the ...
