用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径，缺少圆弧起始角及终止角，并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)

实现图像的拼接与融合，使用SIFT方法，拼接效果较好，例程为两个图片的拼接，实际可实现多个图片拼接(image mosaic)

用块匹配法进行运动估计的matlab实现方法(block matching method used for motion estimation method of Matlab)
