Abstract

The invention discloses a painting-based sketch regularization method and device and a medium, triangulation is performed on a sketch to obtain a triangle set, the triangle set is automatically painted by using randomly generated colors based on a region growing method, and the color of each region is unique; modifying the triangle set after automatic painting according to a first input instruction; deleting the corresponding strokes according to a second input instruction, then supplementing the missing strokes, and finally simplifying the coarse-grained lines into the width of a pixel to obtain a simplified pixel image; and generating a vectorized line network according to the simplified pixel image, fitting each vectorized line in the vectorized line network by using a Bezier curve, and obtaining a hierarchical image by using a backtracking method. According to the method, the stroke simplification and regularization of the existing sketch picture are quickly realized through interactive clicking of the user, so that the subsequent redrawing, color filling, animation processing and the like of the vector diagram are facilitated, and the processing efficiency of the user is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and more particularly, relates to a method, device and medium for regularizing sketches based on coloring. Background technique [0002] With the advancement and development of science and technology, various applications can be installed on mobile terminals, among which image processing applications are very popular among users. Paint specific areas in the sketch. However, in the current processing of sketches, when it is necessary to modify the processed sketches, the operation is troublesome, and the processing efficiency of the user needs to be improved. SUMMARY OF THE INVENTION [0003] The present invention is provided to solve the above-mentioned problems in the prior art. Therefore, there is a need for a sketch regularization method, device and medium based on coloring, which can quickly realize the simplification and regularization of the strokes of existing sketch pictures ...
