Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0035] like figure 1 Shown is a schematic flowchart of a high-naturalness real-time beautifying method in an embodiment of the present invention.

[0036] A real-time beautification method with high naturalness in an embodiment of the present invention includes the following steps:

[0037] Step S100 establishes an image filter convolution template; in some embodiments, the image filter convolution template is a four-layer ring template, and the pixel radius of the four-layer ring in the four-layer ring template from the center of the circle is small to large They are 2 pixels, 4 pixels, 8 pixels, and 16 pixels respectively.

[0038] Step S101 inputs the original image, finds the channel with the least noise in the orig...

Abstract

The invention discloses a high-naturalness real-time beautifying method and device, and the method comprises the steps: employing a single-channel high-contrast image buffing method which employs the channel with the smallest number of interference noise points in three channels r, g and b, and effectively reduces the noise interference from other channels while reducing the calculation amount; obtaining the roughness information of skin through calculating a single-channel high-contrast image buffing image, thereby avoiding the skin distortion caused by the direct filtering of the image, and improving the naturalness of skin; and employing a layer mixing and overlapping method: employing a method of filtering, light softening and brightening mixing and overlapping to achieve an effect of skin buffing and whitening and to maintain the naturalness of the image after a buffing layer is calculated and obtained. The device is used at a mobile intelligent terminal, enables human face to remain natural while beautifying, whitening and buffing the face skin, greatly reduces the buffing track, and enables the reduction degree of edges and shadows of a human face to be high.

Description

technical field [0001] The present invention relates to the technical field of video and pattern beautification, in particular to a high-naturalness real-time beautification method and device. Background technique [0002] Today's mobile terminals, in addition to beautifying when taking pictures, also need beautifying technology when recording videos and chatting. As users have higher and higher requirements for video beautification, in addition to basic skin care and whitening, users also have requirements for natural beautification. So not only do I hope that my skin in the video is good, but I also hope that it can be clearly seen that the skin has been smoothed (by using the layers, masks, channels, filters and other tools in the PS software, in addition to removing the skin part of the people in the picture In addition to the spots, blemishes or variegated colors, it can also smooth the skin of the character's face, which can make the character's face more delicate and...
