Abstract

The embodiment of the invention provides a hand-painted watercolor style drawing method and device. A Sobel operator is adopted to extract an image edge region of an input original image; a trunk edgeimage of the original image is calculated according to the image edge area and the original image; binarization and expansion operation are carried out on the trunk edge image; edge partitioning is carried out on the main edge image after binarization and expansion operation, so that Kuwahara filtering in different radius ranges is carried out on different edge image areas to simulate the drawingcharacteristics of large-area smearing and local sketching in the watercolor; and finally, drawing a hand-drawn watercolor style drawing image of the original image according to the main edge image and the filtering result image. Therefore, the non-edge area has a watercolor painting effect, and image details can be well reserved in the edge area.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a method and device for drawing in a hand-painted watercolor style. Background technique [0002] In daily life, users can use image editing software (such as PhotoShop, etc.) to manually modify images to achieve the effect of hand-painted watercolor paintings, but this method requires users to have a certain art foundation and takes a lot of time. [0003] In the field of computer image processing, various artistic effects including watercolor can be realized at present. Existing watercolor stylization methods based on real images usually use methods such as image edge-preserving filtering or image segmentation to simplify details, and then process the original image through multiple steps such as edge deepening and color dispersion. Although the generated results have the characteristics of large watercolor paintings , but at the same time, the details are too muc...
