1.1 Technique of inputting Chinese character As the structure of Chinese characters are very different from the relatively simple alphabetic system of western languages, it is very difficult to input Chinese characters into computer quickly and conveniently. There are a few existing systems which include those based on the "PinYin" (phonetic) system, a combination of the PinYin system and chara...

We propose a novel method for the skew estimation on text images containing mathematical expressions which can be applied to various characters layouts. Current OCR systems are not capable of recognizing skewed characters in images correctly, and hence skew correction in such images is essential for character recognition. Conventionally methods such as projection profile methods, Hough transfor...

Density analysis plays an important role in font design and recognition. This paper presents a method of density analysis for Chinese characters. A number of density metrics are adopted to describe the density degree of a character from both local and global perspectives, including center-to-center distance of connected components, gap between connected components, ratio of perimeter and area, ...

Reading is one of the best well-practiced visual tasks for modern people. We investigated how the visual cortex analyzes spatial configuration in written words by studying the inversion effect in Chinese character processing. We measured the psychometric functions and brain activations for upright real-characters and non-characters and their inverted (upside down) versions. In the psychophysica...

This document presents a proposal to encode a subset of symbols used in nautical charts. As documented, the characters in this particular subset occur regularly in running text and are therefore suitable to encoding as characters. This document also provides background information on the general nature of symbols used in nautical charts, with particular emphasis on those that appear in publicat...
