Central convergence and stability of BCF vector for Chinese text
Yang Jian-gang · Jisuanji gongcheng · 2005
BCF(Blank Count Feature), a new feature of the construction of projection profile, was presented for Chinese text analysis. BVSA(BCF Vector Smoothing Algorithm), as the preprocessing of projection profile, was presented to be applied before the analysis. After applying BVSA, the projection profile of Chinese text showed an important phenomenon - the convergence of BCF vector. The statistic experiment proved that it was a common and stable phenomenon, and the convergence phenomenon would still be available even if the font style, or font size, or even the text writing/printing style changed. Based on it, the algorithm designed for text line extraction achieved good effect.
