Abstract

The present invention discloses a method for extracting expression information of characters in calligraphy work, belonging to the field of image processing. According to the method, a color space in the calligraphy work to be processed is converted, then the type of the calligraphy work to be processed, which has been converted, is distinguished according to a first channel threshold, and processing is performed according to a distinguishing result indicating that the converted calligraphy work to be processed is a tablet image or a copybook image, so as to obtain an image of character profile information in the tablet image and images of character profile and expression information as well as stamp profile and expression information in the copybook image. The method of the present invention avoids the defect of uncomplete character information caused by edge detection in the prior art, increases detail expression of the detected character information, and improves convenience for research of calligraphy works.
