去模糊的算法，有MIT做的，参考文献是siggraph06的文章，效果很好(Go fuzzy algorithms, MIT has to do the references are siggraph06 the article, very good)

说明：  对于单基地SAR，使用BP算法进行成像，展示回波信号幅度、相位、距离压缩后以及最后成像的图像。(For single base SAR, BP algorithm is used to image, which shows the amplitude, phase, distance compressed and final image of echo signal.)

遗传算法与FCM算法相结合实现图像分割，分割精度较好，速度较快(A combination of genetic algorithm and FCM algorithm to achieve image segmentation, segmentation accuracy is better, faster)

基于matlab的高帽变换，能很好地对图像进行一定的处理，实现图像的增强，线性特征的提取，为后续的处理做准备(Matlab-based top-hat transform good image processing, image enhancement, linear feature extraction, to prepare for subsequent processing)

掌纹图像双峰法二值化，边界跟踪提取掌纹轮廓线，harris角点，手动提取关键点建立坐标系和画正方形(Palmprint image bimodal binary, boundary tracking extract palmprint contour, harris angle manually extract key point to establish a coordinate system and draw a square)

通过阈值去噪，最关键的就是要确定最佳阈值T 的大小.如果阈值太小，可以保留更多的小波系数，但同时噪声也被保留；相反，阈值太大，可以消除更多的噪声，但重要图像特征又将被滤掉，引起偏差.目前使用的阈值分为全局阈值和局部阈值.全局阈值对各层所有的小波系数或同一层内的小波系数都是统一的；局部阈值则是根据当前系数周围的局部情况来确定合适的阈值，具有灵活性.(Threshold denoising, the most critical is to determine the optimal threshold T s size. If the threshold is too small, you can retain more of the wavelet coefficients, but the noise was retained the contrary, the threshold is too large, can be eliminatedmore noise, but the important image features in turn be filtered out, causing bias current threshold is divided into a global threshold and local threshold. global Threshold the wavelet coefficients of all the wavelet coefficients of the layers or on the same floorare unity local threshold is based on the local situation of the current coefficient around to determine the appropriate threshold, with flexibility.)

使用规定分布生成空间随机噪声，可以选择噪声类型和参数。(Using the prescribed distribution to generate spatial random noise, we can choose noise types and parameters.)

在matlab的基础上，使用掩膜图像分割出上层图像(On the basis of matlab, mask image is used to segment the upper image)
