一个基于块的纹理合成matlab源码程序

摘　要:舌象中的裂纹是中医舌诊中的重要内容。由于拍摄条件的不同,舌象质量有较大差异,传统的阈值选取方法并不 适用。文中提出一种舌象裂纹检测的自适应阈值选择方法。该方法利用舌象的L 3 a 3 b 色彩特征及区域的分裂- 合并, 对舌象进行区域分割,自适应地选取舌中部区域的色彩值作为阈值,对整个舌象进行裂纹提取。经验证,本方案对不同的 舌象能较好地提取出裂纹,实现舌象裂纹诊断的客观化。-Tongue’ s crack is a very important part of herbalist doctor diagnosis. For the different screen conditions , there are many differ2 ences on the tongue’ s quality. It is not effective to use the t raditional threshold ext raction algorithm. In order to solve this problem , pro2 pose a new adaptive threshold algorithm. Present the segmentation of the image of tongue by using the feature on tongue in the L 3 a 3 b color space and the split- combining algorithm. Then use the threshold , which is the color value ext racted automatically in the middle of the tongue , to detect the crack of the whole tongue. The experiments show that this approach is able to distill the crack effectively to different tongue images , and achieve the objectivity of the diagnosis based on the tongue’ s c

小波变换是一种多尺度信号分析方法，近几年在图像处理领域受到广泛关注，它克服了傅立叶变换的固定分辨率 的弱点，既可分析信号概貌，又可分析信号的细节。相位相关是一种频率域的图像配准参数估计方法，是利用傅立叶变换的 平移、旋转等特性进行参数估计的。在研究多尺度小波分析和相位相关理论的基础上，提出基于小波系数的像素级相位相 关图像配准方法：首先对待配准图像进行小波分解，获得低频小波系数后，再对小波系数应用相位相关进行配准参数估计。 实验结果表明了该方法的可行性和有效性。-err
