Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] A method for image enhancement of automatic lip gloss based on color space, the steps are as follows:

[0044] 1) Perform face recognition and facial features positioning on the image, and calculate the lip contour area according to the position of the left end and the right end of the lips;

[0045] 2) Blur the lip contour area to generate a lip contour blur map;

[0046] 3) According to the probability map of the color space, calculate the probability that each pixel in the lip contour area is a lip, record it as the lip probability map, and combine the lip contour fuzzy map generated in step 2) to calculate the final probability map;

[0047] 4) According to the final probability map and the lip gloss color selected by the filter, the lip gloss is automatically applied to each pixel in the lip contour area, and finally the result ma...

Abstract

The invention relates to an automatic lip gloss image enhancement method based on the color space. The method comprises the following steps that 1, face identification and five sense organ locating are carried out on an image, and a lip contour area is determined; 2, fuzzy processing is carried out on the lip contour area, and a lip contour fuzzy graph is generated; 3, according to a probability graph of the color space, the probability that each pixel in the lip contour area is the lip is calculated, a lip probability graph is generated and is combined with the lip contour fuzzy graph generated in the step 2, and then a final probability graph is obtained by calculation; 4, according to the final probability graph and the lip gloss color selected by a filter, each pixel in the lip contour area is automatically coated with lip gloss, and finally a result graph after being automatically coated with the lip gloss is obtained. Compared with a lip gloss processing method in the prior art, the method has the advantages of being easier to implement, higher in speed, better in identification precision and more applicable to mobile intelligent equipment.

Description

technical field [0001] The present invention relates to an image processing method, more specifically, relates to a color space-based automatic lip gloss image enhancement method. Background technique [0002] Before everyone shares a selfie, the image is blurred and whitened, as well as skin tone, lip gloss, etc. are adjusted. Therefore, how to adjust the lip gloss has become the focus of every image processing software. [0003] Chinese patent application 201210100239.7 discloses a classification method for classifying lips according to their morphological characteristics, a classification map of lips made up of coordinates generated according to the classification method, and analysis of the shape of lips using the image plane and three-dimensional analysis of lips, according to The shape balance of the lips is judged from the two-dimensional analysis information, the three-dimensionality of the lips is judged from the three-dimensional analysis information, and the shap...
