Abstract

An image region segmentation system includes a first detection part for detecting a candidate region for a text region within an image, a second detection part for detecting a white region within the image by carrying out a pattern matching of a matrix including a pixel of the image with predetermined matrix patterns for a set of successive white pixels, and a discrimination part for detecting whether or not the candidate region detected by the first detection part is a text region by checking if a white region is detected in a neighborhood of the detected candidate region.
