Embodiment Construction

[0027] 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 embodiments and accompanying drawings.

[0028] The face image problem skin enhancement method provided by the embodiment of the present invention can be used to enhance the problem skin part in the captured face image, so as to detect the face problem skin more comprehensively and accurately. The method can enhance problematic skin such as acne, melasma, sunburn, freckles, age spots, etc. in facial images. Such as figure 1 As shown, the method includes the following steps:

[0029] Step A: Take a photo of the face in RGB color mode with polarized light. That is, the light source passes through the polarizer A to generate polarized light, and projects the polarized light onto the face. At the same time, the camera passes through the polarizer B to take pictures of the face.

Abstract

The invention discloses a face image problem skin enhancement method, which uses polarized light technology to take pictures, and calculates skin problems through an image processing method, thereby avoiding skin damage caused by taking pictures with ultraviolet light. At the same time, the method has a small amount of calculation and has low requirements on hardware resources, and can be applied to low-end products (such as embedded devices, tablet computers, etc.). The method can particularly well identify acne, chloasma, sunburn, freckles and age spots.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method for enhancing problematic skin in facial images. Background technique [0002] In the field of facial beauty detection, the detector of Canfield Company in the United States has achieved similar functions, but it has higher requirements for hardware. High-end cameras need to be used to capture images, and calculations need to be performed on higher-end computers, and the calculation time is also longer. With the help of ultraviolet technology, the skin testing equipment of the Holland Ober company can distinguish between normal skin and acne, but ultraviolet light is harmful to the human body and depends on human judgment. There are also some domestic companies that make similar products, such as Meice in Shanghai and Langdi in Shenzhen. Although they all have similar functions, the effect is average. [0003] At present, most of the acne enhancement techniques adopt thi...
