| Abstract(in English) | We previously researched a fast full text searching method using word spotting technique. This method needed to segment newspaper image into character images in advance, however it was a difficult issue. Optical character recognition can be applied only if document images are noiseless and are printed in modern technique, but it cannot be applied to old and degraded document images. We propose an image processing method to improve character segmentation. To segment a whole newspaper image into paragraph images, ruled lines are detected using Hough Transform. The paragraph images contain some hindrances for character segmentation such as ruled lines, ruby characters and noises. Our algorithms remove them. The proposed system is tested for 20 paragraph images of historical newspaper. The accuracy of character segmentation is improved to approximately 92%. |
