Embodiment Construction

[0068] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0069] In the embodiment of the present disclosure, on the basis of the localization of the facial feature points, after the local image data of the human face are cut out for beautification processing, according to the localization results of the feature points, the connection lines between the feature points are used as the edges of the local processing , and apply the distance transformation ...

Abstract

The invention relates to a face image processing method and a face image processing device. The face image processing method comprises the steps of calculating the distance change of each pixel point in a local image; calculating the mixed vector value of each pixel point in the local image according to the distance change of each pixel point in the local image; and combining the local image with a face image according to the mixed vector value of each pixel point in the local image. The face image processing device comprises a first calculating module, a second calculating module and a combining module. The face image processing method and the face image processing device have advantages of improving edge smoothness of a combined image, preventing artificiality of the local image after image combination, and improving face image processing effect.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a face image processing method and device. Background technique [0002] With the popularity of Selfie and continuous shooting of mobile devices, smart face beautification technology has gradually developed, especially with the rapid growth of Internet sharing such as personal photo sharing, it has put forward higher requirements challenge. In the related art, Alpha-Blending is an image processing technique for blending source pixels and target pixels according to an "Alpha" blending vector value. However, using Alpha-blending for image synthesis in face intelligent beautification technology is time-consuming, high-efficiency and low. The calculation accuracy of Alpha value needs to be further improved, and some unnatural phenomena will appear during image synthesis. Contents of the invention [0003] In order to overcome the problems existing in the related ...
