Image processing method and device

Abstract

The embodiment of the invention provides an image processing method and device. The method comprises the following steps: according to a special effect processing request for an image, determining a texture map and color brightness adjustment information corresponding to the special effect processing request; extracting texture correlation information and pixel color information of pixel points in the texture map; adjusting pixel color information of pixel points in the texture map based on the color brightness adjustment information; determining target color brightness information of the pixel points in the texture map based on the texture association information and the adjusted pixel point color information to obtain a target texture map; and performing special effect processing on the image by adopting the target texture map. The color of the texture map is adjusted under the condition that the texture effect of the texture map is protected, rich special effect processing effects are provided for a user, and the processing efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and an image processing device. Background technique [0002] In the prior art, when it is necessary to perform special effect processing on an image or video, the image can usually be processed by using a texture map to achieve a special effect. For example, a face image can be processed by using a texture map to achieve a cosmetic effect, and an object image can also be processed by using a texture map. To change the surface texture of the object, you can also use the texture map to add special effects filter effects such as fog effect, ripple effect, etc. to the image. [0003] Users can also usually have color requirements for special effects processing. For example, in the case of performing beauty makeup processing on a human face image, different color makeup effects may be provided to the user. Generally speaking, in order to...

Problems solved by technology

However, preparing texture maps of several different colors requires a lot of work, and the colors that can be provided are limited

However, directly filling the texture map with color will easily cause the texture effect of the texture map itself to be destroyed during the color filling process.
