Embodiment

[0047] figure 1 shows the operation process of the present invention, by figure 1 It can be seen that its specific implementation includes the following steps:

[0048] (1) Data set collection: collect a database of beautiful faces;

[0049] (2) Layer decomposition: Decompose the original face and the database face to obtain the brightness layer, detail layer and color layer;

[0050] (3) Layer dictionary learning: use online dictionary learning to learn layer dictionaries from layer data;

[0051] (4) Layer sparse reconstruction: use sparse coding to reconstruct the original layer to obtain the reconstructed layer template;

[0052] (5) Detail layer enhancement: use the original detail layer to enhance the details of the reconstructed detail layer template;

[0053] (6) Layer fusion: the three reconstructed layers are merged to obtain a beautified face image.

[0054] The concrete steps that step (1) data set of the present invention collects are:

[0055] (1-1) Crawl t...

Abstract

The present invention discloses a face image beautification method which comprises the steps of (1) data set collection of collecting the database of beautiful faces, (2) image layer decomposition of carrying out image hierarchical decomposition on an original face and database faces and obtaining a brightness image layer, a detail image layer and a color image layer, (3) image layer dictionary learning of using online dictionary learning to learn an image layer dictionary from image layer data, (4) image layer sparse reconstruction of using a sparse code to reconstruct the original image layer, and obtaining a reconstructed image layer template, (5) detail image layer enhancement of using an original detail image layer to carry out detail enhancement on the reconstructed detail image layer template, and (6) image layer fusion of fusing three reconstructed image layers to obtain a beautified face image.

Description

technical field [0001] The invention relates to the fields of face image recognition and face image processing, in particular to a method for beautifying a face image. Background technique [0002] "Everyone has a heart for beauty", people's pursuit of beauty has existed since ancient times. Psychological research shows that despite differences in race, culture, and gender, people have a general consensus on what kind of face is beautiful, and the color and details of human face skin are particularly important for the improvement of face attractiveness. These studies are consistent with the common belief that a beautiful face should be smooth and spot-free. [0003] In recent years, with the rapid development of electronic media such as social networks, more and more face images are shared, and the demand for face image processing is also increasing day by day. Although there are already many commercial image processing software available, these software usually require a ...
