Uyghur handwriting verification based on features combination

Due to the lack of rotation invariance characteristics of existing methods for Uyghur handwriting verification which lead to poor results for rotated handwriting samples,and shortage of using scale invariant feature transform(SIFT),this paper presented a method based on features combination with rotation invariance characteristics.The proposed method firstly extracted SIFT feature,then calculated local window feature and combined both of them before being used for handwriting samples of different rotation angles.Experiments show that the proposed method can effectively overcome the impact on identification of the rotation of handwriting samples and is a simple,practical method with favorable performance for Uyghur handwritings.
