Problems solved by technology

[0003] In the prior art, in the process of beautifying the image with the bilateral filter, when the value range kernel calculates the weight, when the surrounding pixels are noise, it will also be given a larger weight. Therefore, since the image details cannot be maintained , making the beauty effect unnatural

Abstract

An embodiment of the invention provides an image processing method. The method comprises the steps of obtaining a to-be-processed image; determining a definitional domain weight coefficient; determining a value domain weight coefficient according to pixel value differences between a neighborhood of a central pixel point and neighborhoods of surrounding pixel points of the central pixel point, wherein the central pixel point is any pixel point of the to-be-processed image; determining a target weight coefficient according to the definitional domain weight coefficient and the value domain weight coefficient; and performing bilateral filtering on the to-be-processed image by adopting the target weight coefficient. An embodiment of the invention furthermore provides a terminal. Through the method and the terminal provided by the embodiments of the invention, the facial beautification effect can be more natural on the basis of keeping image details.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and a terminal. Background technique [0002] With the rapid development of information technology, the use of terminals (such as mobile phones, tablet computers, etc.) is becoming more and more common. As an important application of terminals, taking pictures has become a selling point respected by major terminal manufacturers. At present, in order to obtain better photo effects, beauty technology is widely sought after in photo applications. Most of the existing beautification algorithms use bilateral filters to remove acne from the skin. The bilateral filter can be regarded as a Gaussian filter in essence. The difference from the ordinary Gaussian filter is that the weight coefficient of the bilateral filter is composed of the domain weight coefficient and the range weight coefficient. Among them, the domain kernel determines the w...
