metlab编程实现图像缩放算法，加入了视频转换成图像-the metlab programming image scaling algorithm, added the video to convert images

纯java代码写的sift图片识别算法，欢迎交流指正！图片匹配效果还是可以的，可以直接运行！木有使用opencv、metlab等api-Pure java code written sift picture recognition algorithm, welcomed the exchange correction! Image matching effect, or can, can run! Wood using opencv, metlab etc. api

精确定位metlab的算法源码，供有兴趣的人参考。-Metlab precise positioning algorithm source code, for those who are interested reference.
