\"The discrete cosine transform (DCT) was applied to locate Chinese characters in ink rubbings of ancient Chinese steles (stone slabs with inscribed characters) in order to extract the characters by creating a bounding box in the image reconstructed by the inverse DCT. This work is a sub-project of a Chinese calligraphy bibliotic (analysis of handwriting for authenticity) project which attempts to speculate on possible sources of calligraphic texts used to inscribe Ji Zi Sheng Jiao Xu, an ancient Chinese stele from the Tang dynasty of China. We will be applying computer aided bibliotics to compare the characters in Ji Zi Sheng Jiao Xu and ones in other texts. Thus, we will be extracting hundreds of characters from digitized ink-rubbings of Chinese steles.
