A method and system for identifying signatures and seals

Abstract

The invention discloses a method and system for identifying signatures and seals. The method identifies the area to be identified in the image of the document to be identified through preset reference coordinate points, and then further identifies the area to be reviewed according to the OCR identification technology. According to the image The RGB value divides the area to be reviewed into the seal image, signature font image and overlapping image, and then obtains the reference coordinate position matrix of the pixels corresponding to the seal image, signature font image and overlapping image respectively, and extracts the seal image, signature font image and overlapping image Contour features corresponding to each, the contour features of the overlapping images are respectively spliced ​​to the contour features corresponding to the seal image and the signature font image, so as to obtain the contours corresponding to the completed seal image and signature font image respectively. Therefore, the workload is greatly reduced, the work efficiency and accuracy are improved, and the problem of incomplete contours caused by overlapping areas of signatures and seals is overcome.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for recognizing signatures and seals. Background technique [0002] At present, in the process of on-site power marketing data inspection, it is necessary to check whether the documents conform to the specifications. Among them, the key point is to check whether the approval area of ​​the documents is stamped with a seal that meets the requirements and whether it is signed by the relevant person in charge. [0003] In the traditional technology, the inspectors manually check the documents, and through visual inspection, the documents that do not meet the approval specifications are selected. However, this method not only has a large workload, but also has low work efficiency and low accuracy. Contents of the invention [0004] The present invention provides a method and system for identifying signatures and seals, which are used to solve the above...
