Digital simulation synthesis method of Yunnan out-of-print overlay based on notch

Abstract

The invention discloses an automated Yunnan out-of-print woodcut digital simulation synthesis technology, in particular, a scratch-based Yunnan out-of-print woodcut digital simulation synthesis method. The method includes the following steps of: inputting an image, and performing color clustering processing on the inputted image; layering the image according to the result of a clustering algorithm so as to make every layer only has one color; outputting binary templates and clustered colors of each layer which are applied to subsequent processing; generating a global vector field which reflects the direction of the tangent line of the edge of the image; generating uniformly-distributed streamline patterns according to the vector field so as to guide the arrangement of scratches; mapping the scratches to the patterns, mapping one scratch selected from a real woodcut onto each streamline; generating edge scratches of the image; and adopting a color overprinting method to draw the image so as to draw a colorful Yunnan out-of-print woodcut. The scratch-based Yunnan out-of-print woodcut digital simulation synthesis method of the invention has the advantages of less human-computer interaction and lifelike effects of the woodcut simulation synthesis digital image.

Description

technical field [0001] The invention belongs to digital image synthesis technology, and relates to a digital analog synthesis method based on a notch-based Yunnan out-of-print overlay. Background technique [0002] Yunnan out-of-print overlay prints, referred to as out-of-print overlays, is a kind of woodcut prints with ethnic minority characteristics. It only engraves one layer on one wooden board and prints once, and the colors are cross-overprinted to produce a special effect of overlapping colors. As an extension of woodcut prints, out-of-print overlays also combine different knife shapes and engraving methods to produce different points, lines, and surface inscriptions, and then create pictures through the combination of points, lines, and surface inscriptions; The difference between them is that an out-of-print overprint is multiple overprints of colors on the same board, and the board is no longer usable when the drawing is completed. Based on images, the present in...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automated Yunnan out-of-print overlay digital analog synthesis technology, which solves the current problem that the imitation and synthesis of woodcut prints in the digital image is not true, the human-computer interaction is complicated, and it is limited to black and white woodcut simulation.
