说明：  通过IDL，简单实现灰度变换，彩色变换等基本操作，包括图片打开保存拖拽显示(Simple implementation of gray level transformation, color transformation and other basic operations)

使用IDL编程来实现打开BMP，TIFF，IMG，JPEG，PNG和其他图像，实现缩放，缩放，平移，图像增强，平滑，边缘检测(Using IDL programming bmp, tiff, img, jpeg, png and other images to achieve open and zoom in, zoom, pan, image enhancement, smoothing, edge detection)

对模糊图像进行复原（代码中样例）后，进行ISNR值的计算。由于复原后图像和原图像可能存在对齐问题，而该对齐问题不影响复原结果的主观效果，因此该代码首次考虑这一问题并给出相应的图像对齐及ISNR计算方法。(Restoration of blurred images (sample code), the calculation ISNR values. Due to possible alignment problems and the restored image after the original image, and the alignment problem does not affect the results of the subjective effects of recovery, so the code for the first time to consider this issue and the corresponding image alignment and ISNR calculation.)

用小波工具箱函数实现小波包的分解与重构，非常适合与机械故障特征提取。(Wavelet packet decomposition and reconstruction, and is ideal for mechanical fault feature extraction using wavelet toolbox functions.)

关于图像分块压缩感知，及测量矩阵加权的三篇文章(Three articles on the image block compressed sensing, and measurement matrix weighted)

采用曲率的方法，等间隔三点的大小计算夹角的大小，根据阈值标记指尖指根区域。(Curvature of the methods used, such as the size of three intervals calculated the size of the angle, according to the threshold refers to the root area marked fingertips.)

图像处理，二维小波变化等指导，说明清晰实用。基于MATLAB(Image processing, two-dimensional wavelet change guidance on clear and practical.)

应用灰度共生矩阵求解纹理特征并用熵，相关性，惯性矩，能量，局部平衡等参数带有实例照片可以直接编译(Applying the grayscale symbiotic matrix to solve the texture features and using entropy, correlation, inertia moment, energy, local equilibrium and other parameters with example photos can be compiled directly.)

图像纹理特征提取，是图像处理中一另一个非常重要的底层特征，matlab实现(Image texture feature extraction, image processing are very important to one another underlying characteristics, matlab implementation)
