| Summary: | 碩士 === 國立交通大學 === 資訊科學學系 === 84 === An intergrated approach to segmentation and understanding
of color magazines is proposed. First, a dynamic-cut color
quantization method is proposed, which can be used to classify
color image contents into more reasonable classes. For block
segmentation, an new algorithm is proposed to grow neighboring
pixels with indentical colors into blocks more efficiently.
After block extraction, several features are used to classify
extracted blocks into text blocks and graphic blocks. For
construction of blocks magazine images which usually have
complicated background, improved methods for merging textblocks
into text areas and graphic blocks into graphic areasare also
proposed.These classified areas are then used to analyze the
document layout. The printorientation of the document is
detected according to the print orientation ofmost textline
blocks. Methods for finding titles, abstracts, section titles,
section texts, headers, footers, page numbers, and captions of
graphics inmagazines are proposed. For multiple-page documents,
methods for linking textcontents and graphics which are in
adjacent pages are also proposed.Experimental results are shown
to prove the feasibility of the proposedapproach.
