Method and device for generating ink painting style image

Abstract

The invention relates to a method for generating images in an ink and wash painting style. The method includes acquiring an original image; blurring the original image to generate a blurred image; detecting the edge of the blurred image to generate an edge image; inverting colors of the edge images to generate a color-inverted image; mixing the blurred image with the color-inverted image according to a first Alpha mixing operator so as to generate a mixed image; reducing the saturation of the mixed image to generate an ink-color image, and performing Gaussian blur for the ink-color image to generate a diffusion image; and mixing the ink-color image with the diffusion image according to a second Alpha mixing operator so as to obtain an image in the ink and wash painting style. In addition, the invention provides a device for generating the images in the ink and wash painting style. The method and the device for generating the images in the ink and wash painting style have the advantages that the processing speed can be increased, and the generated image in the ink and wash painting style has diffusion impression and a blank characteristic and is full of elegant and soft ink and wash lingering charm.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for generating ink painting style images. Background technique [0002] In daily life, in order to make the photos have a certain artistic style after taking pictures, people usually post-process the photos to stylize the photos to generate pictures with artistic effects, such as generating pictures with the style of ink painting. [0003] At present, there are two methods for generating ink painting style images, one is the image processing rendering method (IBR) based on real images, and the other is the model-based non-photorealistic rendering generation method (NPR). [0004] The model-based non-photorealistic rendering generation method needs to model the scene and interact with people to generate it, and requires certain painting techniques to create a satisfactory painting, so it cannot meet the needs of various scenes and automatic processing ,...

Problems solved by technology

[0004] The model-based non-photorealistic rendering generation method needs to model the scene and interact with people to generate it, and requires certain painting techniques to create a satisfactory painting, so it cannot meet the needs of various scenes and automatic processing , is not universal in automatically generating ink paintings

[0005] The image processing and rendering generation method based on real images meets the needs of various scenes. At present, it is generally generated by complex design of real images through image editing software such as Photoshop. This method needs to be completed on the PC side, and requires certain computer and art skills. Basic, time-consuming design, unable to meet the needs of automatic generation
