Abstract

Embodiments of the present application provide a hand-painted watercolor style drawing method and device. The Sobel operator is used to extract the image edge area of ​​the input original image, and after calculating the backbone edge image of the original image based on the image edge area and the original image, the The backbone edge image is binarized and expanded, and by performing edge partitioning on the backbone edge image after the binarization and expansion operations, Kuwahara filtering with different radius ranges is performed on different edge image areas to simulate large-area smearing and painting in watercolor. The local fine-grained painting characteristics are used to obtain the filtered result image. Finally, a hand-painted watercolor style rendering of the original image is drawn based on the trunk edge image and the filtered result image. As a result, the non-edge area has the effect of a large smear of watercolor, while the edge area can well retain image details.

Description

Technical field [0001] This application relates to the field of computer technology, and specifically to a method and device for drawing in 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, 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, a variety of artistic effects including watercolor can be achieved at present. Existing watercolor stylization methods based on real images usually use methods such as image edge preservation 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 resulting result has the characteristics of large watercolor painting , But at the same time, the details are too much smeared out, lacki...
