基于贝叶斯(BAYES)阈值的小波(WAVELET)图像去噪算法源代码IMAGE DENOISING USING BAYES THRESHOLDING OF WAVELET COEFFICIENTS (Based on Bayesian (BAYES) Wavelet thresholding (WAVELET) image denoising algorithm source code IMAGE DENOISING USING BAYES THRESHOLDING OF WAVELET COEFFICIENTS)

一种二维Otsu快速算法的Matlab实现，该算法的原文参见《二维直方图区域斜分阈值分割及快速递推算法》，该文已附在内。(A two-dimensional Otsu fast algorithm Matlab realize that the original algorithm see " Two-dimensional histogram oblique segmentation area and fast recursive algorithm" , the paper has been attached into account.)

图像重采样，根据新旧图像像元大小的比例进行图像的重采样，(This function resamples the images at the new grid points defined by the new pixel sizes. It assumes that intensities are defined at the pixel centers)

提供了基于POCS算法的超分辨率图像重建的源程序，效果较好(POCS algorithm based on super resolution image reconstruction of the source, the effect is good)

YUV420视频的缩放，经过高度的优化，其中三次卷积插值（cubic convolution）算法的效果最好，优化程度也最高。其基本思想是通过整型化、查表等方法消除每一帧图像插值运算中的浮点运算和乘除法运算。(scale YUV420 video frames with cubic, bilinear & cubic convolution interpolation algorithms。)

基于小波变换的图像融合程序，低频采用加权平均，高频采用能量最大准则。(Based on wavelet transform image fusion program, low-weighted average, using high-frequency energy is the biggest criteria.)

estimate shape of a noisy image from the shading information

tiff格式的lena原图，该图像包含了各种细节、平滑区域、阴影和纹理，这些对测试各种图像处理算法很有用。(Lena artwork in TIFF format,The image contains a variety of detail, smooth areas, shadows, and textures, which are useful for testing various image processing algorithms.)

代码主要用来模拟林芝机场附近一天内4个不同时间GDOP变化情况(Code is mainly used to simulate the Nyingchi Airport near four different times within a day GDOP changes)

评价描述子的好坏，能给出重叠率、正确率和查错率等(Evaluation of descriptors)
