Problems solved by technology

However, there are few mature image whitening algorithms. Whitening is not a characteristic description of an image. Simply increasing the brightness of an image or other parameters cannot achieve a good whitening effect. Moreover, the whitening effect of existing whitening algorithms is not good, and the processing effect is too high. stiff

[0023] figure 1 It is an implementation flowchart of the method for quickly processing images provided in the first embodiment of the present invention. The method can be executed by a device for rapidly processing images, wherein the device can be implemented by software and / or hardware, and can be built as a part of the smart terminal Inside the smart terminal. Such as figure 1 As shown, the implementation process includes:

[0024] Step 11. Perform whitening processing on the image to be processed to obtain a whitened image.

[0025] Wherein, the image to be processed may be an image captured by a smart terminal (such as a smart phone and a tablet computer, etc.). The smart terminal can use a whitening algorithm to process the pixel values ​​of the pixels in the image to be processed to obtain a whitened image. Compared with the image to be processed, the whitening image improves the skin color of the person in the image, increases the degree of whitening, eliminates da...

Abstract

An embodiment of the invention relates to the field of image processing technologies, in particular to a method and a device for processing image rapidly. The method comprises the steps of: carrying out whitening processing on an image to be processed to obtain a whitened image; carrying out color balance processing on pixel points in the whitened image to obtain a color-balanced image; and adjusting contrast and brightness of the pixel points in the color-balanced image to obtain an adjusted image. According to the method, the image to be processed is subjected to whitening processing to achieve initial whitening of the image to be processed, then the whitened image is subjected to color balance processing, so that image color distribution is balanced, factuality of the image is increased, and the contrast and brightness of the color-balanced image are adjusted at the same time, thereby improving the influence of insufficient light on processing effect.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a method and device for rapidly processing images. Background technique [0002] In recent years, with the rapid development of smart phones, people's needs for mobile phone functions have become more and more diverse. Among them, an important function of smart phones is Selfie. Photos taken with mobile phones can be used in many fields such as making avatars and sharing on social networks. Realizing the beautification processing of selfie images on smart phones is the focus of people's attention, and the most basic beautification processing must include image smoothing and image whitening. [0003] Image microdermabrasion algorithms are relatively mature, and the more successful ones are Gaussian blur and bilateral filtering algorithms. However, there are few mature image whitening algorithms. Whitening is not a characteristic description o...
