柔性内窥镜用于许多诊断和介入手术。生理运动可能使医生的任务非常难以执行。可以通过使用机动内窥镜和实时视觉跟踪算法自动跟踪选定的目标来实现辅助。为了控制电机，需要对内窥镜视图中的目标的运动进行准确的估计，这需要有效的跟踪算法。在本文中，我们比较现有的跟踪算法在各种体内目标，以评估其在不同条件下的行为。研究表明，在活体环境中跟踪算法必须克服的几个问题，如照明变化和向前/向后运动的目标。
Flexible endoscopes are used in many diagnostic and interventional procedures. Physiological motions may render the physicians task very difficult to perform. Assistance could be achieved by using motorized endoscopes and real-time visual tracking algorithm to automatically follow a selected target. In order to control the motors, one needs to have an accurate estimation of the motion of the target in the endoscopic view, which requires an efficient tracking algorithm. In this paper, we compare existing tracking algorithms on various in vivo targets in order to assess their behavior under different conditions. The study shows that several issues have to be overcome by tracking algorithms in in vivo environment like illumination change and forward/backward motions of the target.
