Abstract

The embodiment of the invention relates to a face target area detection method, device and apparatus, and the method comprises the steps: obtaining an original image with a human face, binarizing the original image, and extracting a to-be-processed image of the human face; in the Lab color space, performing color value quantization on all pixels of the to-be-processed image to obtain a quantized image; and according to the pixel value of a target color in the Lab color space, determining a target area in the quantized image, the target area being used for detecting the skin state of the face. According to the embodiment of the invention, the color value is enhanced through the color enhancement operation, and the color feature is further enhanced through the color value quantization operation, so that the target area can be better extracted.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of detection equipment, and in particular to a method, device and equipment for detecting a facial target area. Background technique [0002] With the rapid development of mobile communication technology, various smart terminals are widely used in people's daily life. People will use APP and other software to get a preliminary understanding of some health problems. Skin problems, such as acne, pigmented spots and pores, can effectively reflect human health. [0003] In the prior art, face detection can be performed by an image processing detector, but it is easily disturbed by the image background, the face area extraction is inaccurate, and red areas other than the face are prone to appear, and the extracted red color features are single , the extractable color feature information is insufficient, resulting in low accuracy of red zone detection. Contents of the invention [0004] T...
