Localization of Uyghur Character in Image Based on Wavelet Transform

Halidan·Aa,Kuerban·Maitimushab(a.College of Electrician Engineering;b.College of Artistic Design,Xinjiang University,Urumqi 830049,China)  
Based on the analysis of Uyghur character structure features,this paper studies the characteristics of Uyghur character in wavelet transform and according to these characteristics it presents a localization method of Uyghur character in the video image based on wavelet transform.By using local time-frequency and multi-scale featured wavelet analysis method,distinguished texture features with different space resolutions and the edge components with different directions sub-image are extracted.Then by mathematical morphology method,the useless information is greatly decreased and the ultimate target text region is acquired.Experiments show that the proposed method can detect text effectively and is suited for the localization of Uyghur characters in complex background.
