Hand-sketching graph pseudo-break-point eliminating method and hand-sketching graph pseudo-break-point eliminating system

Abstract

The invention relates to a hand-sketching graph pseudo-break-point eliminating method and a hand-sketching graph pseudo-break-point eliminating system. The method includes the steps of 1, reading and preprocessing a touch-screen hand-sketching graph so as to obtain x-coordinate values and y-coordinate values of all non-zero pixel points; 2, obtaining a shortest path track from a starting point to an end point of the touch-screen hand-sketching graph, and obtaining x-coordinate sequence data and y-coordinate sequence data of all points in the shortest path track; 3, sampling, estimating and correcting the x-coordinate sequence data and the y-coordinate sequence data respectively to obtain x-coordinate mean value sequence data and y-coordinate mean value sequence data; 4, taking the x-coordinate mean value sequence data and the y-coordinate mean value sequence data as x-coordinates and y-coordinates to be connected into a curve which is a desired corrected touch-screen hand-sketching graph with pseudo break points eliminated. The hand-sketching graph pseudo-break-point eliminating method has the advantages that data change rate is provided in processing results, data change characteristics are revealed, and necessary data are provided for data analysis methods depending on the data change rate.

Description

technical field [0001] The invention relates to a method and system for eliminating false breakpoints of hand-drawn graphics. Background technique [0002] Hand-drawn graphics, also known as sketches, are a common way for designers to express their design intentions in conceptual design. It provides designers with a platform to show design thinking and carry out creative design work. But the ambiguity of hand-drawn graphic information and the randomness of user input hinder the development of hand-drawn graphic recognition technology. With the continuous improvement of computer software and hardware performance, the rapid development of computer graphics, pattern recognition, artificial intelligence and human-computer interaction and other disciplines, many institutions at home and abroad have carried out related research on sketch recognition based on human-computer interaction technology. Many representative recognition methods, such as stroke-based and primitive represen...

Problems solved by technology

[0011] The disadvantage of the current method is that it directly uses the hand-drawn graphics data to extract different pixels and then reconstructs the hand-drawn graphics. The performance of these methods will be directly affected by the false vertices in the hand-drawn graphics.
