Abstract
An image data processing method, a system and an electronic device are provided. The method includes: recording to-be-processed database data as a target image set; performing sharpness calculation on target images in the target image set by a weighted gradient algorithm, and removing, if sharpness of at least one target image is smaller than a threshold, the at least one target image from the target image set; performing sharpness enhancement processing on remaining target images in the target image set; extracting feature points in the target images in the target image set and the contrast image, one by one or at intervals; and comparing and judging similarity between the target images and the contrast image by a similarity algorithm, and inputting similar target images into classified storage spaces.
