Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] The present invention provides a non-realistic rendering method for images, such as figure 1 shown, including the following steps:

[0048] S101. Extract regions of interest (Regions of Interest, ROI for short) in the source image;

[0049] S102. Perform watershed transformation on the region of interest, and divide the image of the region of interest into multiple subregions;

[0050] S103. Process each sub-region through a Mean-Shift algorithm, and ...

Abstract

The application discloses an image non-photorealistic rendering method and system. The method includes the following steps: extracting a region of interest in a source image; carrying out watershed transformation on the region of interest, and segmenting the region-of-interest image into multiple sub regions; processing each sub region through a mean shift algorithm, and filling the processed subregions with color; and fusing the colored sub regions and smoothing the edges to get a non-photorealistic rendered image. In the application, through the introduction of a region-of-interest extracting technology to image analysis, the redundant information of the image is eliminated to a certain extent, the primary content of the image is highlighted, the interference brought by secondary content is eliminated, the image NPR time efficiency algorithm is improved, and a non-photorealistic artistic image of a water color style is realized. Moreover, manual intervention in the processing process is reduced as much as possible, and a friendly user interface is provided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image non-realistic rendering method and system. Background technique [0002] Non-Photorealistic Rendering (NPR for short) is an image processing technology that uses computers to generate hand-painted styles. It is a brand-new field in computer graphics and image processing. One of the research hotspots. At present, NPR technology is widely used in many fields, such as art, digital entertainment, film and television production, scientific medicine and industrial design and other fields. NPR technology research at home and abroad has been able to realize the simulated creation of various works of art, for example, using computers to simulate artistic effects such as watercolor paintings, ink paintings, and oil paintings. [0003] In the practical application of image non-photorealistic rendering technology, it is not only required that NPR processing has a good art...
