A method and system for eliminating false breakpoints in hand-drawn graphics

Abstract

The present invention relates to a method and system for eliminating false breakpoints of hand-drawn graphics. The method includes step 1: reading and preprocessing the hand-drawn graphics on the touch screen to obtain the abscissa values ​​and ordinate values ​​of all non-zero pixel points; 2: Obtain the shortest path trajectory from the starting point to the end point of the hand-drawn graphics on the touch screen, and obtain the abscissa sequence data and ordinate sequence data of all points in the shortest path trajectory; Step 3: respectively analyze the abscissa sequence data and ordinate sequence data Carry out sampling, estimation and correction to obtain the abscissa average sequence data and the ordinate average sequence data; Step 4: Connect the abscissa average sequence data and the ordinate average sequence data as the abscissa and ordinate respectively to form a curve, which is the desired The touch-screen hand-painted correction graphics that eliminate false breakpoints. The data change rate is provided in the processing result, which reveals the change characteristics of the data, and provides necessary data for many data analysis methods that utilize 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.
