A Linear Subspace Learning Approach via Sparse Coding

星载合成孔径雷达干涉测量的经典书籍，王超(book for InSAR)

image and signal processing are used mostly right now. these programs is related to image processing. Image negative is used for the getting the negative image of the original image. and contrast stretching is for the give the middle value. Fast Fourier Transform program is used for the getting FFT of the signal.
