1. A fast face beautifying method for digital images, comprising the following steps of:

  • step 1;

    reading an original image locally or remotely;

    step 2;

    performing Gaussian blur to the original image to obtain a blurred image;

    step 3;

    sequentially extracting a green channel value G of a single pixel of the original image, and performing linear light blending to the green channel with a corresponding pixel of the blurred image to obtain a first green channel value G1;

    step 4;

    performing continuous hard light blending to the first green channel value G1 obtained by linear light blending with the its own G1 to obtain a second green channel value G2;

    step 5;

    combining the second green channel value G2 with a red channel value R and a blue channel value B both obtained by Gaussian blur, to obtain a third green channel value G3;

    step 6;

    performing color mapping to the original image to obtain a whitened image;

    step 7;

    performing skin color recognition to the original image to obtain a corresponding skin color probability value; and

    step 8;

    using a product of the third green channel value G3 by the corresponding skin color probability value as a transparency, performing transparency blending to the original image and the whitened image to compose a beautified image.
