The frequency domain plays an important role in image processing to smooth, enhance, and detect edges of images. Although image data typically does not include imaginary values, the fast Fourier transform (FFT) has been used for obtaining spect

Lossless image compression plays a very important role in image processing. However, it develops very slowly and it is difficult to improve the efficiency of compression, since complete information and high fidelity are demanded. The lossless compres

本程序模拟了存在像差时候的波面的衍射模式，对研究波前畸变对光束的影响具有重要作用-This procedure simulated when the existing aberration of the wave diffraction pattern, to the research of the wavefront aberration on the influence of the beam plays an important role

Image segmentation plays an important role in computer vision and image processing applications. The motivation of this project is Image Segmentation with the presence of Intensity inhomogeneities. Intensity inhomogeneity often occurs in real world
