PCA1

低秩学习，rpca，适用于图像去噪，视频跟踪。(low rank learning,rpca,image denoise.Image tracking)

说明：  多站拼接后三维激光扫描点云的消冗处理,多站拼接后三维激光扫描点云的消冗处理(After more than three-dimensional laser scanning station splicing point cloud processing eliminate redundant, multi-dimensional laser scanning station splicing eliminate redundant processing point cloud)

图像分割方法，可以自动获取目标图像的边界，并且可以有效分割灰度不均匀图像(The level set segmentation method can automatically obtain the boundary of the target image, and can effectively segment inhomogeneity image.)

说明：  本程序是基2的时间抽取FFT变换，可以将信号从时域转换到频域。(This procedure is the base 2 time extraction FFT transform, can transform the signal from time domain to frequency domain.)

裁剪shape文件，使用idl编程实现，就是一个功能，编译以后可以直接调用这个函数(Clipping shape file, using idl programming, is a function, after compiling can directly call this function)

基于拉haar小波的图像增强，与传统直方图均衡化相比较，效果更好。(Pull-based haar wavelet image enhancement, with the traditional histogram equalization compared to better.)

说明：  在Matlab下，使用二元树复小波进行图像检索(Texture retrieval using DT CWT)
