Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] like figure 1 Shown, a kind of method of fast optimization skin color of the present invention, it comprises the following steps:

[0031] 10. Receive the image to be processed, and perform grayscale calculation on the image to be processed to obtain a grayscale image;

[0032] 20. Obtain the average gray value of the image to be processed, and use the average gray value as the transparency to calculate the transparency of the image to be processed to obtain the best skin color;

[0033] 30. Perform soft-light mixed mode processing on the image...

Abstract

The invention discloses a method for quickly optimizing skin color, which obtains a grayscale image by performing grayscale calculation on the image to be processed, obtains the average grayscale value of the image to be processed, and uses the average grayscale value as the transparency of the image to be processed. The transparency is calculated to obtain the best skin color, and then the image to be processed and the best skin color are processed in a soft-light blending mode to obtain a soft-light image, and finally the grayscale image is used as a mask, and the Transparency calculations are performed on the image to be processed and the soft light image to obtain the result image; thus, non-skin areas such as hair can be automatically not processed, and there is no need to identify and extract skin areas. The operation is convenient, and the grayscale image is used as the mask. version and combined with soft light processing technology, making the processed skin color more natural.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for quickly optimizing skin color during image processing. Background technique [0002] With the development of image processing tools, more and more images are edited and beautified by image processing tools to obtain desired images. In the process of editing and beautifying images with people as the main body, it is often necessary to process the skin color to achieve the beauty effect of skin color transformation. For example, the skin color processing may be whitening processing, that is, using an image processing tool to whiten the face area in the image. [0003] However, the current processing of skin color is mainly to adjust the curve of the whole picture, which is to deal with the whole picture, so that the hair and other areas will also be adjusted, and it is impossible to adjust only for the skin color area; or, there are also only for the skin color area. How...
