Method and device for image processing

A device for image processing, characterized in that, the device comprises:

• a processor and a memory, wherein a plurality of executable modules including a facial recognition module, a determination module for skin area, a determination module for skin blemish and a removal module for skin blemish are stored in the memory, which are executable by the processor to process an image;
• wherein,
• the facial recognition module which is executed to perform facial recognition on the image to be processed;
• the determination module for skin area, which is executed to determine a skin area to be processed in a facial area according to detection results;
• the determination module for skin blemish, which is executed to determine the locations of skin blemishes in the skin area to be processed;
• the removal module for skin blemish, which is executed to remove the skin blemishes in the facial area according to the determined locations of the skin blemishes in the skin area to be processed to obtain a processed image;
• the determination module for skin blemish comprises:
• an obtainment submodule for images with different levels of conspicuousness, which is executed to obtain images with different levels of blemish conspicuousness for the skin area to be processed;
• a generation submodule for skin similarity image, which is executed to determine color values of the skin area to be processed and generate a skin similarity image for the skin area to be processed according to the color values;
• a determination submodule for skin blemish, which is executed to determine the locations of the skin blemishes in the skin area to be processed according to the images with different levels of blemish conspicuousness and the skin similarity image;
• the obtainment submodule for images with different levels of conspicuousness comprises:
• a first image generation unit, which is executed to perform a first grayscale processing on the skin area to be processed to generate a first image with a first black/white contrast;
• a second image generation unit, which is executed to perform a second grayscale processing on the skin area to be processed to generate a second image with a second black/white contrast wherein the first black/white contrast is greater than the second black/white contrast, and the way of the second grayscale processing is different from that of the first grayscale processing;
• a third image generation unit, which is executed to firstly perform a dermabrasion processing on the skin area to be processed to obtain a dermabrasion-processed image, and then to perform a third grayscale processing to the dermabrasion-processed image to generate a third image with a third black/white contrast wherein the third black/white contrast is the same as the first black/white contrast, and the way of the third grayscale processing is identical with that of the first grayscale processing;
• the determination submodule for skin blemish comprises:
• a generation unit for first set of skin blemishes, which is executed to generate a first set of skin blemishes according to the second image, the skin similarity image and the skin area to be processed;
• a generation unit for second set of skin blemishes, which is executed to generate a second set of skin blemishes according to the first image, the skin similarity image and the skin area to be processed;
• a generation unit for third and fourth set of skin blemishes, which is executed to generate a third set of skin blemishes and a fourth set of skin blemishes according to the third image, the skin similarity image and the skin area to be processed;
• an obtainment unit for skin blemish, which is executed to combine the first to fourth sets of skin blemishes together to obtain the locations of all the skin blemishes in the skin area to be processed.
