Embodiment Construction
[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0066] The overall idea of the present invention is to propose a pigment separation method based on optical density space-based centralized image channel difference. The color skin image is extracted from the skin color, and then the image is divided into several sub-image blocks, and the sub-image blocks containing non-skin pixels are discarded; 2. The acquisition of the best pure color densi...
