基于matlab的高分辨距离像的研究 svm实现(high ratio radar magic basic on matlab)

此M文件主要利用区域生长和边缘检测进行图像分割(image segment by region grow )

说明：  可见光影像的密集匹配，很经典的算法，效果也非常理想(image matchingimage matching)

用于各种特征提取主成分分析法，如表情提取，人脸提取，识别分类等(For a variety of features to extract the principal component analysis (pca)，Such as expression extraction, face extraction, identification classification, etc)

包含了主要的图像质量评价的matlab源程序。图像熵，图像的方差和，以及基于边缘检测算子的质量评价函数。(Contains the main image quality evaluation of the matlab source code. Image entropy, variance and images, as well as edge detection operator based on the quality of the evaluation function.)

这是一个很好的彩色图像分割源代码，实验结果不错，希望对大家有帮助(This is a good color image segmentation source code, experimental results well, want to help everyone)

采用FDTD时域有限差分法计算电磁波的传播问题等,(The finite difference time-domain (FDTD) method is used to calculate the propagation of electromagnetic wave.)

说明：  编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本，在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别；对于延拓版本，比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)
