Method and system for image path generation

Abstract

The invention, which relates to the target path generation field in image processing, discloses a method and a system for image path generation. The method comprises the following steps that: a to-be-processed area in an image is determined by a click position; image edge detection is carried out on the to-be-processed area to extract corresponding image boundary information; a to-be-processed boundary is obtained according to a boundary image and a boundary chain of the to-be-processed boundary is generated; according to the click position and a gradient image in the boundary information, a digraph of the boundary chain is generated; a shortest path generation algorithm is employed to extract a shortest path; and path curve fitting is carried out to obtain a needed result path is obtained. According to the method provided by the invention, determination is carried out on local image information to complete generation of an image path; and a forced operation point is arranged during an operation process, so that an operator can automatically adjust a state of path generation; and thus the quality of the path generation can be ensured.

Description

technical field [0001] The invention relates to the field of object path generation in image processing, in particular to an image path generation method and system. Background technique [0002] Currently, image paths are mostly drawn using the "pen tool". With the pen tool, the operator uses a fully manual method to operate the segmented edge of the image to complete the drawing and generation of the path. The path is generated by using the "pen tool". The operator needs to complete the drawing of the path segment by segment according to his subjective judgment of the image content, and manually adjust the existing path and the previous path in real time during the drawing process. Shape, to ensure that it can better fit the edge, and the transition between each path is smooth and natural, so as to obtain a higher quality of path generation. The method of manually drawing the generated path can guarantee the quality of the generated path, but due to the manual operation,...

Problems solved by technology

Therefore, it is difficult to adjust the details of the generated path after adopting the method of "selection to path" and completing the path generation by this method, so the quality of the image path generated by this method is difficult to be guaranteed
