Embossment style rendering method

Abstract

The invention discloses an embossment style rendering method. Three-primary-color separating is carried out on an original image, and three-primary-color parameters are established; by means of convolution fuzzy processing, color gradation evenly changes, and the image is prevented from being locally shaded or overexposed; adjustment function processing is carried out on the image parameters, and the sense of layering is intense; an image with the embossment effect is output, the image outline is clear, and the image has a three-dimensional effect.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a rendering method of relief style. Background technique [0002] The existing rendering technology of relief effect is mainly based on 2D image grid and adjacent color difference. The usual algorithm in actual rendering is based on: the actual algorithm of relief effect is based on the deviation value between adjacent pixels. However, for most images, the difference between adjacent images is not large, and only taking the difference between adjacent pixels will make the image tend to be black (darker). The difference between two adjacent pixels Add a scaling constant to add some brightness to dark areas. In the traditional rendering algorithm based on relief effect, no smoothing filter and adjustment function are provided, resulting in the rendered original image showing the characteristics of uneven color scale and weak layering. [0003] In the field of graphics and image pr...

Problems solved by technology

Based on the traditional relief effect rendering algorithm, no smoothing filter and adjustment function are provided, resulting in the original image after rendering, showing the characteristics of uneven color scale and weak layering

[0003] In the field of graphics and image processing, traditional realistic image processing and non-realistic image processing are currently a hot spot in computer graphics and image processing; 3D non-realistic image rendering is generally based on 3D models using exaggerated, linear, etc. Methods to process the geometric texture of the model, and some use the color value of the texture to re-light to obtain the rendering effect of the non-realistic image. These processing methods and algorithms are often more complicated

The traditional non-realistic relief style image is obtained based on 2D image grid processing. Although the processing principle is relatively easy to understand, it has the disadvantages of uneven color scale and poor relief effect.
