Title:
TEXT IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/118356
Kind Code:
A1
Abstract:
A text image processing method and apparatus. The method comprises: preprocessing a text image to obtain a binary image and multiple connected domains comprised in the binary image (210); obtaining, by means of a convex hull algorithm, convex hulls corresponding respectively to the multiple connected domains and character regions externally connected to the convex hulls (230); performing horizontal-direction character segmentation on the obtained character regions to obtain multiple character blocks distributed in the binary image (250); and merging the character blocks according the heights of the character blocks in the binary image to obtain blocks comprised in the text image (270). The text image processing method and apparatus can improve the versatility and the accuracy of character segmentation.
