Abstract

The disclosure discloses an image relocation method and device and belongs to the field of image processing. The image relocation method includes the following steps: establishing a significance model of an image; according to the significance model, calculating significance values of pixel points in the image; according to the significance values of the pixel points, calculating total significance values of pixel lines; and according to a target size of the image and the total significance values of the pixel lines, relocating the image. Problems, which exist in related technologies, that during relocation of an image, non-redundant information of an original image needs to be analyzed and the analysis process is overly complex and the calculation quantity is significantly large are solved, and an effect that the calculation quantity is reduced significantly is achieved.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular to an image relocation method and device. Background technique [0002] An image usually contains some redundant information, which occupies part of the capacity. In order to reduce the capacity occupation of the redundant information in the image, an image retargeting (image retargeting) technology can be used to eliminate the redundant information in the image. Commonly, an image relocation technology based on a seam carving algorithm can be used to remove redundant information in the image. [0003] In the process of image relocation based on the line clipping algorithm, firstly, the color feature vector of the pixel in the original image is obtained, and then the color feature vector and the non-redundant information of the original image, image resolution, etc. are considered comprehensively. Factors, use these factors to determine the pixel lines composed of pixels wi...
