CvTermCriteria criteria,intflags ); OK,KLT算法的原理基本就这样,其实其跟踪效果并非太准,后来有很多提出的校正的方法,其中我目前看到比较实用的就是TLD算法的作者Zdenek Kalal在他2010年ICPR上的文章Forward-Backward Error: Automatic Detection of Tracking Failures提出的方法看起来非常不错,我正动手实现之。
A multi-core multi-thread based Kanade-Lucas-Tomasi (KLT) feature tracking method includes subdividing an input image into regions and allocating a core to each region; extracting KLT features for each region in parallel and in real time; and tracking the extracted features in the input image....
We propose vision-based interface for mobile devices by tracking 3D motion of a human fingertip using a single camera and by recognizing small input gestures in the air. Since the fingertip near the camera moves fast in the image, a high-frame-rate camera is used for stable tracking. In or...

To test the accuracy of this automated process, the inferior vena cava of 47 spontaneously breathing patients were measured by trained ultrasound physicians and compared against the results obtainedviathe automated tracking. Good agreement between the techniques was found, with intra-class correlation ...
