Abstract

The invention relates to the technical field of image processing, and provides a target segmentation method and device, and the method comprises the steps: carrying out the detection of a connected region of a preprocessed image, obtaining at least one first connected region, and obtaining an external rectangle corresponding to each first connected region, and obtaining the rectangular informationof the external rectangle; When the rectangular information corresponding to the first communication area is consistent with the preset form information, determining the first external rectangle corresponding to the first communication area as a target external rectangle; When the rectangular information corresponding to the first communication area is inconsistent with the preset form information, obtaining a second communication area, determining a second communication area from the at least one first communication area, dividing and screening the second communication area to obtain a thirdcommunication area in which rectangular information of the external rectangle is consistent with preset form information, and taking the external rectangle corresponding to the third communication area as a target external rectangle; carrying out Target segmentation on the to-be-processed image according to all the target circumscribed rectangles. The problem that the adjacent targets in the SARimage cannot be accurately segmented is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, to a target segmentation method and device. Background technique [0002] Due to the special mechanism of SAR (Synthetic Aperture Radar) microwave imaging, SAR can perform active imaging under any atmospheric and lighting conditions, and has the characteristics of all-weather and all-weather work, making SAR images more and more demanding in a large number of military and civilian applications. more and more. The development of high-precision and high-efficiency SAR image detection and recognition methods has become a hot research topic for scholars at home and abroad. [0003] In the prior art, the obtained image, such as the SAR image, has the phenomenon that the target is contiguous, which cannot be accurately segmented, resulting in inaccurate target recognition. Contents of the invention [0004] The object of the present invention is to provide a target s...
