Most motion-based tracking algorithms assume that objects undergo rigid motion, which is most likely disobeyed in real world. In this paper, we present a novel motion-based tracking framework which makes no such assumptions. Object is represented by

目的 利用 CT、 MR等获得的图像 ,重构出器官、 骨骼或组织的三维形体 ,帮助医生诊断、 治疗或制订手术方案。方法hear2Warp 算法通过将三维数据场的投影分解为错切变换( shear ) 和变形变换(warp)两步来实现三维重建 ,显著减少了计算量。先对体数据进行错切变换 ,然后在错切空间根据阈值法获取三维表面 ,根据光照模型得到三维表面的亮度 ,最后通过变形变换得到最终的结果图像。-The purpose of the use of CT, MR and other availabl

晚上开着的树莓派老亮着那盏红色电源指示灯，感觉非常不舒服，狠想关掉它！我还是比较喜欢把麒麟座上的RGB灯调成蓝色做小夜灯，毕竟往上照射的灯光不会让人感觉不舒服。
将以下几行加到 /boot/config.txt 即可禁用树莓派 Model 2B 的两盏指示灯。(The raspberry pie that was on at night was always lighting the red power indicator. It was so uncomfortable that it wa
