Description: 毫米波图像存在分辨率低的缺点，该程序在WRLA算法的基础上，进一步采用投影算法，能有效改善毫米波图像的分辨率-Images acquired from Passive Millimeter-Wave (PMMW) radiometer have poor resolution due to limited aperture dimension. Therefore, Super-Resolution Algorithm (SRA) is a key component for PMMW imager. SRA realizes spectrum extrapolation, however, spectrum in-band is deteriorated too. Wiener-Richardson-Lucy Algorithm (WRLA) recovers spectrum in-band by Wiener filter, and extrapolates spectrum out-of-band by Richardson-Lucy Algorithm (RLA). WRLA can avoid spectrum deterioration in passband, but its ability for spectrum extrapolation is limited also. We propose an improved algorithm to solve this problem. This algorithm, which has built constraints according to characteristics of PMMW imaging, uses Projection-Onto-Convex-Sets (POCS) technique to enhance the WRLA s performance, so it is termed as POCS-WRLA.

Description: 我们提出一个新的方法，方法噪声，用来估计和比较数字图像去噪方法的表现。我们首先对一个广泛的去噪算法类计算和分析方法噪声，称之为局部平滑滤波。其次，我们提出一种新的基于图像中所有像素的非局部平均的算法，非局部平均（NL-means）。最后，我们展示几组实验比较非局部平均算法和局部平滑滤波算法。-We propose a new method for noise method used to estimate the performance of digital image denoising methods and compare. We first noise, a denoising algorithm calculation and analysis method called partial smoothing filter. Secondly, we have proposed a new algorithm based on all the pixels in the image non-local average, the non-local average (NL-means). Finally, we show several groups of experiments comparing non-local averaging algorithm and the local smoothing filter algorithm.

Description: LEE Filter for SAR Speckle reduction
im：SAR影像
w_size：窗口大小，奇数 3 5 7 9等
out_size：输出图像的大小，可以是 same 或者 full
NL：number of Looks，等效视数
bound：边缘扩展模式，分为 symmetric ， replicate , circular 。
flag：计算时是否包含中心像素，0为不包含，1为包含。
bound和flag主要是给im_mean_var用的 :)
im_ret：滤波结果
-LEE Filter for SAR Speckle reduction im: SAR imaging w_size: window size, and other odd 3579 out_size: output image size, can be ' same' or ' full' NL: number of Looks, ENL Number of bound: Edge Extended mode is divided into ' symmetric' , ' replicate' , ' circular' . Flag: whether to include the calculation of the center pixel, 0 is not included, one to contain. Bound and the flag is mainly used to im_mean_var :) im_ret: filtering results
