Problems solved by technology

[0004] Currently commonly used edge detection operators (such as Sobel, Roberts, Prewitt, Laplacian, Canny, etc.) can detect the edges of images to a certain extent, but for accurate comparison and scoring of two images, the edge contours detected by these operators are too rough

Embodiment Construction

[0040] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0041] The overall implementation process of the present invention, as attached figure 1 As shown, before the computer grades the painting, the user needs to select the album of stick figures, draw according to the above illustration, and input the painting through the computer camera. Get the score by running the scoring algorithm from step 2 to step 6. If the score is not satisfactory, redraw it. If the score is satisfactory, perform intelligent coloring. Random colors are generated through the probability model, and the outline of the stick figure is drawn in color to complete the computer-assisted generation. paintings.

[0042] as attached figure 2 As shown, the edge extraction of the image can be performed through the Canny operator, and the process is as follows:

[0043] 1. Convolve the image with a Gaussian function with a scale of σ

[0044] 2. For each pixe...

Abstract

The invention provides a stick figure computer scoring and auxiliary coloring method. The method comprises the steps that step 1 a hand drawing and a template map are loaded, and normalization adjustment of size and sliding window weighted smoothing are carried out; 2 the image edge and the contour are extracted to acquire the optimal threshold and the optimal contour; 3 the optimal contour is used to replace the original contour in an image, and a clear image contour is acquired through expansion and corrosion; 4 the contour is extracted again and saved as a second-layer contour; 5 the extracted contour is decomposed into sub-contours, the center position of the sub-contours is calculated to form a deformation model for the relative distance between the centers; 6 contour matching is carried out, and the area and the deformation position the sub-contours are constrained to acquire a comprehensive score; and 7 pseudo-color coloring is carried out on the contour of the original painting. The method can promote intelligent man-machine interaction, stimulates children to learn a painting interest, and has an important application value in the field of children's education.

Description

technical field [0001] The invention relates to a computer scoring and auxiliary coloring method for a stick figure, in particular to a computer scoring and auxiliary coloring method for a stick figure based on an outline strengthening and deformation constraint model, belonging to the field of digital image processing. Background technique [0002] Stick figures have always been an important subject in art classes for kindergarten and elementary school students. Because of its wide selection of materials, rich content, and clear painting logic. Children can easily get started and finish quickly. Learning stick figures can exercise children's aesthetic sense and aesthetic consciousness from an early age, and at the same time train the coordinated development of related organs such as eyes, hands, and brain. [0003] In view of the fact that there is no scoring system for stick figures for children, in order to help children learn stick figures more effectively, a computer ...
