Abstract

The invention provides an image repositioning method, device and terminal, and belongs to the technical field of computers. The method comprises the following steps: building a significance model of an original image; calculating the significance value of each pixel dot in the original image according to the significance model; repositioning a targeted image according to the significance value of each pixel dot, the original resolution of the original image and the target resolution of the targeted image. The device comprises a model building module, a value calculating module and an image positioning module. With the adoption of the image repositioning method, device and terminal, the problem that analyzing the content of the original image to obtain an important image dot is complex and leads to large calculating load is solved, and the effect of lowering down the calculating load is reached.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an image relocation method, device and terminal. Background technique [0002] Image retargeting technology is an image processing technology that compresses, deforms or crops redundant information in an image based on image content. 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 using the line clipping algorithm, the terminal first obtains the color feature vector of each pixel in the original image, and determines the redundancy in the image according to the color feature vector and parameters such as the image content and image resolution of the original image. Pixel lines composed of pixels with higher degrees of density; the determined redundant pixel lines are cut out to obtain a relocated image. [0004] During the process of im...
