medical image thresholding using modified SFLA

通信专业中滤波算法中有关信噪比计算的matlab编程。(Communication professional in filtering algorithm Matlab programming signal-to-noise ratio.)

此算法为基于k-means聚类的非局部均值快速去噪算法，方法便捷有效，可保持边缘信息(this is a fast edge-preserving denoising method based on non-local means method with k-means clustering)

说明：  图像融合指标，综合熵、空间频率、互信息等等，一共7种。在图像处理后的质量评价方面很有用(Fusion index, comprehensive entropy, spatial frequency, mutual information, etc., a total of 7 species. In the image processing is useful for quality assessment)

各种图像质量评价方法，非常适合图像的客观质量评价。(All kinds of image quality uation method, it is very suitable for objective image quality uation.)

小波包去噪C + +源代码，包括信号小波包分解，，最优树的选择，并重建一个,可以直接使用。 (Wavelet packet denoising C++ source code, including the signal wavelet packet decomposition, the optimal choice of the tree, and rebuild a can be used directly.)

说明：  区域生长法的图像分割方法，效果分厂不错，值得借鉴！(Region growing image segmentation method, the effect of a good factory, worth learning!)

论文介绍了一种SFS 算法的参数估计及其实现。它在考虑自遮掩影响的情况下, 有效地估计了SFS 算法中涉及的各种控制参数, 并引入亮度约束、灰度梯度约束和可积性约束, 计算出表面高度和表面向量, 实现三维重构。最后还指出了在Matlab 中实现需要注意的问题。(The paper introduced a SFS algorithm parameter estimation and its implementation. It under the condition of considering the covering effect, estimates the SFS algorithm effectively involved in all kinds of control parameters, and introduces brightness constraint, gray level gradient constraint and the integrability of constraints, calculate the surface height and surface vector, realize the three-dimensional reconstruction. Finally, points out the problems requiring attention is realized in Matlab. )
