Abstract

The invention discloses an image processing method and device, and belongs to the field of mobile communication. The method comprises the following steps: acquiring an overall zoom coefficient of an original image; determining a target scaling coefficient group enabling a target energy function to be minimum according to the total scaling coefficient, wherein the target energy function is used forrepresenting the difference between the adjusted image and the original image, the target scaling coefficient group comprises a target scaling coefficient of each triangular mesh of the original image, the triangular meshes are meshes obtained by triangulating the original image, the target scaling coefficient is obtained by adjusting the overall scaling coefficient according to the significancevalue of the triangular mesh; and according to the target zoom coefficient group, carrying out zoom processing on pixel points in each triangular mesh to obtain a target image. According to the embodiment of the invention, the problem that image distortion is easily caused in a picture zooming process in the prior art is solved.

Description

technical field [0001] The present application belongs to the field of mobile communication, and in particular relates to an image processing method and device. Background technique [0002] With the rapid development of mobile communication technology, various mobile electronic devices and non-mobile electronic devices have become indispensable tools in all aspects of people's lives. The functions of various application programs (Application, APP) of electronic equipment are also gradually improved. They no longer simply play a role in communication, but provide users with various intelligent services, which bring great benefits to users' work and life. Great convenience. [0003] At present, picture-related functions have become one of the main functions of electronic devices, and users use electronic devices to take pictures, browse pictures, and even perform picture processing operations. In the process of image browsing or image processing, image zooming is often perf...
