Problems solved by technology

Image processing methods that are only constrained by color or space are unable to accurately adjust a region of interest in the image because they do not combine the color and spatial characteristics of the image, and it is easy to cause image distortion

Abstract

The present invention relates to an image processing method, comprising the following steps: obtaining an image to be processed, and obtaining a region of interest of the image to be processed; analyzing the region of interest to obtain the spatial characteristics and color of the region of interest feature; construct a spatial mask according to the spatial characteristics of the region of interest, and construct a color similarity mask according to the color characteristics of the region of interest; and use the spatial mask and the color similarity mask The combined mask is obtained by weighting the combined mask; the image is processed using said integrated mask. The invention also provides an image processing device. The invention can accurately process the region of interest and reduce image distortion.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] Due to the needs of picture and photo processing effects, many image processing software will adjust the color of the image to achieve some special effects, such as "filter" effect. The method of adjusting the color of an image is usually a color transformation. The color transformation is to perform continuous function mapping transformation on the image in color spaces such as RGBA, YUV, LAB and other color spaces. Color transformation usually only uses the color information of the image, and the transformation result is only constrained by the original color information of the image and the transformation method, and has nothing to do with the spatial coordinates of each pixel of the image. Other processing of the image, such as changing the shape and position of the image through distortio...
