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

Abstract

The invention discloses an automated Yunnan out-of-print overlay digital simulation synthesis technology, which inputs an image and performs color clustering processing on the input image; according to the results of the clustering algorithm, the image is layered so that each layer has only one color; This step outputs the binary template of each layer and the clustered color of each layer for subsequent processing; generates a global vector field that reflects the tangent direction of the image edge; generates a uniformly distributed streamline diagram based on the vector field , to guide the placement of notches; notch mapping, each streamline is attached with a notch taken from a real woodcut painting; generate edge notches of the image; use color overprinting method to draw the image, thereby drawing a colorful Out-of-print engraving in Yunnan. The beneficial effects of the invention are that there is less human-computer interaction, and the effect of woodblock print simulation and synthesis of digital images is realistic.

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.
