数字图像处理用到的标准测试图像，很多图片。(IMP test images。)

方向梯度直方图的全部代码，广泛应用于行人检测行人检测(Histogram of Oriented Gradients code Pedestrian Detection)

直方图均衡、小波增强、contourlet变换用作图像增强(Histogram equalization and wavelet enhancement, contourlet transform is used for image enhancement )

运行程序，得到不同伽马因子给图像的整体明暗程度带来的变化(Run the program to get the change of the overall brightness of the image with different gamma factors)

说明：  GOME-2数据反演叶绿素荧光算法代码，添加文件为GOME-2 level 1b级数据时，得到的Fs数组即为反演结果(Code of chlorophyll fluorescence algorithm retrieved from GOME-2 data)

一个基于Gabor滤波器组的多特征融合的图像检索算法（CBIR based on Multi-Features Combining Multi-parameters from Gabor Filter-bank, 简称multi法），融合了基于Gabor 小波系数的标准方差，峰态，能量，平滑度和一致性度量五个特征量度，实验表明，该算法是一种更加有效的图像检索方法。(we propose a CBIR algorithm based on Multi-Features Combining Multi-parameters from Gabor Filter-bank(called multi algorithm for short), which use Gabor filter banks and combine five features including standard deviation, kurtosis, energy, smoothness and uniformity together. The results of experiments show that this algorithm is a more effective method used for image retrieval.)

移动窗口算法平滑光谱矩阵，用于近红外等光谱数据的预处理(Moving window spectral matrix smoothing algorithm for near-infrared spectral data, such as the pretreatment)

对图像进行二值化处理的源代码，编译后的可执行文件须带参数运行),非常好的代码.欢迎使用和下载!呵呵,真的,不信下下看啊!(two pairs of images of the value of the source code, compile the executable files carry parameters run), very good code. welcome to download and use! Oh, really, do not look at the next letter ah!)

自适应正则化超分辨率重建 是： M. G. Kang这人写的IEEE上发表的论文 可以参考下算法( General Choiceof the Regularization Functional in Regularized Image Restoration)

计算两幅图像之间的交叉熵，自己编的比较简单和大家分享。(Calculate the cross-entropy between the two images, their own series is relatively simple and to share.)
