一个关于hough和radon变换的实例,实现了时钟图形做图.(and one in Chinese on hough transform examples and achieve a clock graphic graphics.)

两个图像质量评价函数，psnr峰值信噪比，正则均方误差nmse，能可用于去噪图像和压缩图像的质量评价，很有用啊。(Two image quality evaluation of the function. Including psnr PSNR, it is mean-square error nmse other. Images can be used for de-noising and compression of image quality evaluation.)

本文档主要用于图像的倾斜矫正，通过建立透视变换矩阵和强角点检测实现畸变图形的矫正(This document is mainly used for Image tilt correction, through the establishment of perspective transformation matrix and strong corner detection, to achieve distortion correction)

此文件实现了自适应UKF和UKF算法对运动刚体的位姿估计，采用噪声估计器在线估计过程噪声的均值和方差，避免了人为设定噪声的统计特性。(This document implements adaptive UKF and UKF algorithm to estimate pose and pose of moving rigid body, and uses noise estimators to estimate the mean and variance of process noise online, avoiding the statistical characteristics of man-made noise.)

说明：  基于MODIS 大气水汽的计算，大气水汽含量(Atmospheric Water Vapor Calculation Based on MODIS)

说明：  图像超分辨率是指从一序列低分辨率观测图像中重建高分辨率图像。图像超分辨率充分利用了各帧图像 间相似而又不同的信息。(Compared with the model derived from Kolmogorov spectrum, the new model introduces more complete transcendent constraints and is more similar to the physical characteristics of atmospheric turbulence.)

说明：  MATLAB读取envi的raw格式高光剖数据(Matlab reading the raw data of envi)

运用Perona-Malik各项异性扩散模型对二维图像进行去噪处理。该方法在有效的抑制噪声的同时能够保护图像的边缘。(The use of Perona-Malik Anisotropic Diffusion Model for the treatment of two-dimensional image denoising. The method in the effective suppression of noise at the same time to protect the edge of the image.)

说明：  该文件可以读取MRI raw data，磁共振指的是自旋磁共振（spin magnetic resonance）现象。其意义上较广，包含核磁共振(nuclear magnetic resonance, NMR)、电子顺磁共振（electron paramagnetic resonance, EPR）或称电子自旋共振（electron spin resonance, ESR）(The file can read MRI raw data, Magnetic resonance refers to the phenomenon of spin magnetic resonance. It is broader in meaning and includes nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) or electron spin resonance (ESR))

用于灰度图像二值化的MATLAB代码，算法采用迭代法(For gray-scale image binarization MATLAB code, algorithm uses iterative method)
