| 摘 要： | 针对文本依存的离线笔迹鉴别,提出一种基于纹理的算法.该算法采用Gabor变换对纹理进行分析,选取4个频率8个相位,通过变换,选取32维变换系数的方差作为笔迹特征,在分类时使用欧氏距离作为分类器,并且提出一种新的阈值获取方法,针对该算法进行实验得出,正确接受率为89.3%,正确拒绝率为80.0%.

| Abstract: | This paper presents a context dependent method of off-line handwriting verification based on the texture feature.Gabor filter is used in the texture analysis to gain handwriting features.By choosing 4 frequencies and 8 directions,it will get 32 Gabor coefficients,and this paper chooses the variance of coefficients as handwriting feature.The Euclidean distance is applied as classifier,and a new technique for getting threshold value is proposed in this paper.Experimental results show that the correct acceptances rate is 89.3% and the correct rejections rate is 80.0%. |
