Embodiment Construction

[0042] As mentioned earlier, video surveillance has been more and more widely used, and surveillance cameras can be seen in shopping malls, streets, intersections, and public transportation distribution centers. After the portrait image is obtained through the camera, processing and recognizing the obtained portrait image has also become a commonly used technology in surveillance. However, the efficiency of processing and recognition of portrait images is currently low, and the recognition accuracy rate needs to be improved.

[0043] In the embodiment of the present invention, the sorting based on image quality is completed for different image data of the same object, and the image data whose image quality is within the preset ranking range is stored after each sorting, thereby reducing the amount of stored data and saving storage space; Process the stored image data to extract the feature data of the shooting object, which reduces the amount of processed data and improves the...

Abstract

The invention relates to an image recognition method and system. The image recognition method includes the following steps that: objects of which the area is within a preset range are tracked and photographed, so that image data can be obtained; the image data of the same object are sequenced based on image quality obtained through photographing; image data of which the image quality is within a preset ranking preset range are stored after each sequencing; and the stored image data are processed, so that the feature data of the photographed object can be extracted. With the image recognition method and system adopted, the efficiency of image recognition and the correctness of the recognition can be improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image recognition method and system. Background technique [0002] Video surveillance has been used more and more widely, and surveillance cameras can be seen in shopping malls, streets, intersections, and public transportation distribution centers. After the portrait image is obtained through the camera, processing and recognizing the obtained portrait image has also become a commonly used technology in surveillance. [0003] However, the efficiency of processing and recognition of portrait images is currently low, and the recognition accuracy rate needs to be improved. Contents of the invention [0004] The technical problem solved by the invention is how to improve the efficiency of image recognition and the accuracy of recognition. [0005] In order to solve the above technical problems, an embodiment of the present invention provides an image recognition method, includ...
