Abstract

The invention discloses a drawing method and device for sketching. The method comprises the following steps of acquiring a selected image, and carrying out gray processing on the selected image to obtain a processed image; according to the gray value of pixel points in the processed image, establishing the gray distribution curve of all pixel points in the processed image; dividing all pixel points of the processed image into several groups by taking the minimum points in the graph as segmentation points; normalizing the gray value of each pixel point located in the same group to obtain the average gray value of each group; according to the position of pixel points in each group in the processed image, determining the corresponding drawing line sub-paths of each group, and determining thedrawing times of each drawing line sub-paths according to the average gray value of each group; according to the drawing times of each drawing line sub-path and each drawing line sub-path, calculatingthe total drawing line path, and drawing the sketch map of the selected image according to the total drawing line path. By implementing the embodiment of the invention, the sketch map of the selectedpicture can be automatically drawn according to the selected picture, and the sketch map of the selected picture can be obtained.

Description

technical field [0001] The invention relates to the field of computers, in particular to a sketch drawing method and device. Background technique [0002] Using charcoal, pencils, pens, etc. to draw a monochrome picture of light and shade with lines, it is called sketch. Sketch is a formal artistic creation. It uses monochrome lines to express things in the intuitive world, and can also express ideas, Concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It does not focus on the overall and color like the painting with color, but on the structure and form. [0003] However, existing sketches require people who have a certain foundation in painting to create, and the quality of sketches largely depends on the level of painting of the creators, and people without a foundation in painting cannot create sketches. Contents of the invention [0004] Embodiments of the present invention provide an automatic sketching method and device, which can automatical...
