Jia Juan, Ibm China · Zhongwen xinxi xuebao · 2005
Detecting reading order for text layout exclud ed by image is a key problem in document image understanding (DIU) and text typese tting. Especially in Chinese and other orient languages, text region in which wo rds are reflected to next line when they meet a graph boundary makes reading ord er various. A new layout model, which uses a new page object called PMRegion, is defined. Based on ordered tree, an algorithm for reading order detection after page top-down decomposition for constructing layout objects is presented. They are proven be effective by a special typesetting system and also helpful to go d eep into DIU.
