METHOD FOR DETECTING SIMILAR UNITS BASED ON OUTLINE BELT GRAPH

摘要

A method for detecting similar units based on an outline belt graph involves following steps: S1, demarcating one of the similar units of a image to be detected by utilizing a stroke and demarcating a background area of the detected image; S2, segmenting the demarcated image to be detected, extracting a sample of the similar units, removing the background area of the image to be detected, and reserving a foreground area consisting of the similar units; S3, acquiring an outline graph from the foreground area, and obtaining a potential object outline boundary in the image; S4, constructing an outline belt graph within the range of an area adjacent to outline points in the outline graph; S5: matching the sample of the similar units with the outline belt graph, and determining the position of the similar units in the detected image. The method enables searching and positioning the similar units in the image according to a simple prompt input by users, and applying detection results to editing operations based on scene object level in the image, such as image rearrangement, editing communication, synchronous deformation, and the like.
