Abstract

The present invention provides an image processing method and device, wherein the method includes: acquiring an image to be processed, determining a first area in the image to be processed, where the first area is an area containing a preset object or a preset area; Brightness blur processing is performed to obtain the first image; the outline of the first area in the first image is extracted, and based on the outline of the first area, the brightness discrimination threshold of the outline boundary is calculated, and based on the brightness discrimination threshold, all the objects in the first image are determined The contour boundary information of the contour; perform coarse quantization processing of the brightness information of the image to be processed to obtain the second image; use the contour boundary information of all contours in the first image to enhance the contour boundaries in the second image, and obtain the processed Image. Embodiments of the present invention improve the filter shooting effect of images by adopting a contour extraction mechanism and increasing a brightness quantification level mechanism, thereby effectively solving the problem of excessive pitting in the filter shooting effect of existing images.

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] Smart terminal camera application is a very widely used function. In order to improve the practicability of the camera application, many image processing functions are embedded in the application, and filters are one of them. However, the filter in the prior art is limited by the simplicity of its design device, and the processing effect is often unsatisfactory. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an image processing method and device, aiming at solving the problem in the prior art that the obtained effect image is not clear due to the simple design of the filter in the application of the smart terminal camera. [0004] An embodiment of the present invention provides an image processing method, including: [0005] Acquire ...
