The invention relates to a category cluster center determination method and device, computer equipment and a computer readable storage medium, and the method comprises the steps: obtaining an original image in an image file, and the shooting time and shooting place of the original image, and obtaining the image features, time features and geographic position features of the original image; and based on the features, obtaining image correlation, time correlation and space correlation between every two original images, carrying out weighting processing on calculation results of the correlation in the three aspects, and obtaining comprehensive correlation between every two original images so that the original image with the comprehensive correlation exceeding a preset correlation threshold value is screened out to serve as the class cluster center of the image file. Video monitoring effective data are fully mined, the image features of the original image are utilized, the time features and the geographic position features of the original image are also utilized, the correlation in the three aspects is comprehensively considered, the high-quality image is screened out to serve as the class cluster center, and the file falling accuracy is effectively improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, computer equipment and computer-readable storage medium for determining cluster centers of clustered files. Background technique [0002] A kind of key technology is involved in the clustering of portrait files: cluster center representation of portrait files. The portrait images captured by the front-end equipment need to be archived eventually, and the portrait images need to be compared with the base archives for similarity, and the matching files are found and archived. However, the calculation of similarity with each image in the archive is too computationally intensive. At this time, a cluster center is needed to represent the archive. The image to be archived only needs to calculate the similarity with the cluster center of each archive. Can. The quality of the cluster center is directly concerned with the accuracy of the drop-off...
