Art stylization image processing method

Abstract

The invention discloses an art stylization image processing method. The art stylization image processing method comprises the steps of: performing simple graph expression generation processing on an input real image; performing and-or graph expression generation processing on the result of the simple graph expression generation processing; performing stroke distribution graph generation processing on the result of the and-or graph expression generation processing to obtain a needed image. According to the invention, the drawbacks such as a bad layering effect, inflexible rendering and complex man-machine interaction operation in the prior art can be overcome, and the advantages of a good layering effect, flexible rendering and simple man-machine interaction operation are realized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an artistic stylized image processing method. Background technique [0002] Non-photorealistic rendering refers to the technique of using computers to generate graphics that are not photorealistic, but have a hand-drawn style. Its goal is not the authenticity of graphics, but mainly to express the artistic characteristics of graphics, to simulate works of art (even including defects in works) or as an effective supplement to realistic graphics. The main simulated paintings of non-photorealistic rendering include oil painting, watercolor painting, pen drawing, pencil drawing, ink painting and cartoon animation. Using this method based on computer simulation drawing can greatly reduce manual participation, reduce drawing costs, and improve the popularity of artistic style works. [0003] The current main technique of non-photorealistic rendering is based on artis...

In addition, even if the height information is added to simulate the oil painting bump texture, such as Figure 5 As shown, it is quite different from the texture effect formed by the accumulation of oil paint, which can be easily distinguished by the naked eye. The image moment method pays too much attention to the local area information of the image, and the stroke size is basically less than 25 pixels, otherwise the stroke will not be able to Cover the entire canvas, so the above computer simulation effect is quite different from the hand-painted oil painting effect, and it cannot completely replace the hand-made oil painting process. Even if there is a product available, it has not yet had a great influence

[0050] In the process of realizing the present invention, the inventors found that there are at least defects in the prior art such as poor layering effect, inflexibility of rendering and complicated manual interactive operation
