| Abstract(in English) | We deal with distinction between handwritten and machine-printed characters in document images. Current distinction techniques need extraction of characters and text lines from document images. However, the extraction is difficult if document images have handwritten characters. To solve the problem, we propose a distinction method inspired by human vision system. We transform every local region in document images into frequency domain data, and extract feature values which include fluctuations caused by handwriting. For the distinction, we employ a multilayer perceptron which learns the feature values. Experimental results show that our method doesn't need to locate characters or text lines. In addition, we analyze condition for the distinction experimentally. |
