Embodiment Construction

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is further described below with reference to the accompanying drawings.

[0050] In this example, see figure 1 As shown, the present invention provides an automatic acne detection method, which includes steps: S100-S500.

[0051] S100 acquires the original image I_rgb.

[0052] S200 obtains the skin color binarization map of the original image by filtering the skin color of the original image and locating the key points of the face.

[0053] like figure 2 As shown, the step S200 includes steps S210-S260.

[0054] S210 skin color detection: use skin color detection algorithm to detect skin color on the original image I_rgb, obtain a single-channel skin color probability map SKIN_MAP, the pixel value range is [0, 255], SKIN_MAP has the same resolution as I_rgb; wherein the skin color detection algorithm adopts conventional algorithm.

Abstract

The invention discloses an automatic pimple detection method. The method comprises steps that S100, an original image is acquired; S200, skin color filtering and face key point positioning of the original image are carried out, a binary skin color graph of the original image is acquired; S300, the binary skin color graph is utilized to extract a connected pimple zone; S400, according to the connected pimple zone, pimple zones of the original image are coarsely detected; and S500, the pimple zones are screened, and the accurate pimple zones are acquired through screening according to local pimple characteristics. The method is advantaged in that the pimples, moles and relatively obvious speckles on a face can be automatically and accurately detected, the method is simple and reliable, computational complexity is low, and the beauty effect can be realized in combination with a subsequent pimple removal method.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an automatic acne detection method. Background technique [0002] In recent years, with the advancement of technology, mobile devices such as smartphones and tablets have become indispensable digital entertainment tools for people. With the rise of smart devices, the demand for beauty selfies is also growing, and many users hope to remove some acne, moles, etc. on the face. [0003] However, many existing applications need to manually click on the acne area to achieve the effect of removing acne, which is a cumbersome process; even if there is an automatic acne removal method, it still cannot be removed for more obvious acne and larger moles. . [0004] In addition, LOG, DOG and other methods commonly used for spot detection in the prior art usually require a large amount of calculation, and there will be many false detections for acne on a human face.
