SIFT

igmt one of geo-image software

常用数字图像处理，图像变换等功能的实现，锐化平滑等算法(digital image processing)

实现RGB到HSV空间转换，之后提取H、S、V分量后获取图像的颜色直方图和累计颜色直方图。(Achieve RGB to HSV space conversion, after the extraction of H, S, V components to obtain the image of the color histogram and cumulative color histogram.)

说明：  图像修复算法 使用criminisi算法对破损图像进行修复。(The image restoration algorithm uses criminisi algorithm to repair the damaged image.)

说明：  对24位的彩色图像用中位切分(中位区分）法将其转换成8位索引图像，并且生成对应的颜色查找表。(median-cut algorithm,8-bit index map, lookup table,256 colors,)

带通配符的字符串匹配,多重匹配,支持通配符“*”，“？”(String matching with wildcards, multiple matches, supports wildcards " *" , " ?" )

利用该函数可以对图像进行仿射变换，是不错的matlab源代码(Function can make use of the image affine transformation, is a good source code matlab)

图像匹配，可以实现目标图像的匹配，匹配出最相似的训练图片。(Image matching, the matching can achieve the target image, matching the most similar training images.)

基于块匹配的稳像算法，包括演示视频，非常全面，希望对大家有帮助(Stabilization based on block matching algorithms, including a demonstration video, very comprehensive, we hope to help)
