Problems solved by technology

However, spots on the face (such as moles, acne, wounds, etc.) affect the appearance and are usually elements that users do not want to show
[0003] At present, some software can provide the function of freckle removal, but there are also some problems: 1) the degree of automation is not enough, and the user needs to manually select the spots, which is a heavy workload; 3) The traces of spot filling are obvious, or complex algorithms such as Poisson fusion are used, and the timeliness is poor

Embodiment Construction

[0048] In the existing technology, some software can provide the function of freckle removal, but there are also some problems: the degree of automation is not enough, the user needs to manually select the spots, and the workload is heavy; the missing and false detection of spots is serious, resulting in unsatisfactory freckle removal effect in the later stage; The traces of spot filling are obvious, or complex algorithms such as Poisson fusion are used, and the timeliness is poor.

[0049] In the embodiment of the present invention, the face image is subjected to high-contrast preservation processing, and a threshold value is used for binarization, so that strong edge contours such as spots and facial features can be detected as much as possible, thereby avoiding misdetection of areas other than the face as The area where spots need to be removed, and the detection rate of spots is improved; according to the skin color probability template and the binary template of the spots,...

Abstract

The invention discloses a face image processing method and device and a readable storage medium. The method comprises the steps: carrying out the face recognition of an image, and determining a face image in the image; calculating a skin color probability template according to the face image; performing high contrast reservation processing on the face image, and performing binarization by using athreshold to obtain a binary template of spots; determining a spot area to be removed according to the skin color probability template and the binary template of the spot; and removing the spot area needing to be removed in a filling mode from outside to inside. By adopting the scheme, the spots in the face image can be quickly and conveniently removed.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a face image processing method and device, and a readable storage medium. Background technique [0002] With the improvement of people's quality of life and the emergence of various social platforms, people pay more and more attention to their clothes and appearance. The emergence of portable mobile devices (such as smart phones) has made selfies and photo shows a fashion in life. Generally speaking, after taking a selfie, the user needs to perform post-processing and other adjustments on the picture, especially for the shooting of face images. However, spots on the face (such as moles, acne, wounds, etc.) affect the appearance and are usually elements that users do not want to show. [0003] At present, some software can provide the function of freckle removal, but there are also some problems: 1) the degree of automation is not enough, and the user needs ...
