Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] Such as figure 1 As shown, a face reduction image generation method with remarkable texture effect, including:

[0038] Step 1. Input the face test photo;

[0039] Step 2, performing edge enhancement processing on the above-mentioned test photos;

[0040] Step 3, performing Laplace sharpening processing on the strengthened test photo;

[0041] Step 4. Use K-NN nearest neighbor search between the test photo and the training photo to obtain a simplified map;

[0042] Step 5, performing denoising processing on the obtained simplified image;

[0043] Step 6. Output the simplified graph.

[0044] Each step is described in detail below:

[0045] (1), input a...

Abstract

The invention discloses a face simple graph generation method with a remarkable texture effect. The method comprises the following steps of step1, inputting a face test photograph; step2, carrying out edge reinforcement processing on the above test photograph; step3, carrying out Laplace sharpening processing on the reinforced test photograph; step4, using K-NN neighbor search between the test photograph and a training photograph so as to obtain a simple graph; step5, carrying out noise removing processing on the obtained simple graph; and step6, outputting the simple graph. A purpose of enhancing a texture effect of the simple graph is realized.

Description

technical field [0001] The invention relates to the technical field of computer graphics and image processing, in particular to a method for generating a simplified human face image with remarkable texture effects. Background technique [0002] A simple diagram, that is, a sketch diagram as it is usually called. Sketching is arguably one of the closest forms of art that requires only a drawing tool, some paper, and the willingness to do creative work. But many people do not have basic art training, and with the popularity of digital cameras and smart phones, ordinary digital photos can no longer meet people's needs, and converting digital photos into photos of other art forms has become a part of daily life. way of entertainment. [0003] Regarding the synthesis of parsimonious graphs, there are generally two basic methods, image-based methods and sample-based methods: [0004] The image-based face parsimony map synthesis method generates strokes and shadows according to ...
