Petreatment of Images of Xiangxi Hmong Characters
摘要
Abstract
Hmong characters in Xiangxi is used in the Hmong area of Xiangxi.But there is still a research gap for its machine identification.The pretreatment of Hmong character images is a prerequisite for the identification and it will directly influence the effect of image characteristic extraction and identification. The pretreatment proposed involves graying of character images through weighted average method,bina-rization through Ostu algorithm,and image smoothing and uniformization based on the combination of Homomorphic and the improved median filtering.This pretreatment constitutes the basis for the image i-dentification of Hmong characters in Xiangxi.关键词
