Embodiment 1
[0042] refer to figure 1 , figure 1 is a schematic flowchart of a method for processing a face image according to an embodiment of the present invention.
[0043] In Embodiment 1, the method for processing a human face image includes:
[0044] Step 101, converting the image to be processed from RGB color space to HSV color space;
[0045] Specifically, the color image collected by the camera is converted from the RGB color space to the HSV color space. In the RGB color space, the three color components all contain brightness information and are correlated, and have poor adaptability to brightness. In the HSV color space, the chroma, brightness, and saturation can be well separated, and there is less overlap with non-skin color points.
[0046] Step 102, acquiring the skin color region of the image to be processed according to the threshold value of the H component in the HSV color space;
[0047] Preferably, the acquiring the skin color area of the image to be processed...
Embodiment 2
[0069] refer to figure 2 , figure 2 It is a schematic diagram of the functional modules of the device for processing human face images according to the embodiment of the present invention.
[0070] In Embodiment 2, the device for processing human face images includes:
[0071] Conversion module 201, for converting the image to be processed from RGB color space to HSV color space;
[0072] Specifically, the color image collected by the camera is converted from the RGB color space to the HSV color space. In the RGB color space, the three color components all contain brightness information and are correlated, and have poor adaptability to brightness. In the HSV color space, the chroma, brightness, and saturation can be well separated, and there is less overlap with non-skin color points.
[0073] The first acquisition module 202 is configured to acquire the skin color region of the image to be processed according to the threshold value of the H component in the HSV color sp...
