用数字图像处理主要是为了修改图形,改善图像质量,或是从图像中提起有效信息,还有利用数字图像处理可以对图像进行体积.(Using digital image processing is mainly graphics in order to modify and improve the image quality, or from the image to bring effective information, as well as the use of digital image processing can be carried out on the image size.)

ENVI是比较常用的遥感图像处理软件，使用该插件，可以使ENVI软件支持HDF5格式的遥感影像，HDF5数据格式是科学计算一体化数据格式，常用于卫星遥感影像的外部存储。(Envi is more commonly used in remote sensing image processing software, use the plugin can enable envi software support the HDF5 format of remote sensing images, the HDF5 data format is scientific computing integration data format, commonly used in satellite remote sensing image of the external storage. )

实现了对误拍角度的矫正，基于轮廓提取以及旋转矩阵变换实现图像错误识别和矫正(It realizes the correction of misalignment angle, and realizes image error recognition and correction based on contour extraction and rotation matrix transformation.)

说明：  采用积分图算法的归一化互相关匹配，大大减少了计算时间。(Normalized cross correlation matching)

打开24位彩色bmp文件, 显示该图像 将图像内容顺时针旋转90度后显示出来 将图像分成等大小的4块，将第1和第3块像素互换后保存 将旋转后的图像转换成灰度图像显示，并保存 对灰度图像求Sobel边缘图，显示出来，并保存 对灰度图像进行Gaussian平滑，并保存（需要体会平滑的作用） 对灰度图像进行2值化(Open 24-bit color bmp files, displays the image will rotate clockwise image content displayed image is divided into four equal-sized 90 degrees, the first and three pixels after swap to save the rotated image conversion ashes of the image display, and save images to grayscale seeking Sobel edge map is displayed, and save the gray image Gaussian smoothing, and save (experience required smoothing effect) grayscale image binarized)

本程序的作用，完成了一种图像的DDE算法，数字图像细节增强。(The role of this procedure, the completion of an image of the DDE algorithm, digital image detail enhancement.)
