一个图像拼接框架。切换注释与未注释代码可实现不同检测器与描述子的组合。默认使用SURF+BRIEF，通过预设重叠区域比例排除非重叠区域特征点的检测，提升特征点检测速度，减少误匹配。(An image stitching frame. The switching annotation and the non - annotated code can implement the combination of different detectors and descr iptors. Using SURF+BRIEF by default, the detection of non overlapping region feature points is eliminated by setting default area ratio. The detection speed of feature points is improved and mismatch is reduced.)
