Abstract

While a tracking system is unaware of the identity of any object it tracks, the identity remains the same for the entire tracking sequence. Our system leverages this information by using accumulated joint cooccurrences of the representations within the sequence to create a hierarchical binary-tree classifier of the representations. This classifier is useful to classify sequences as well as individual instances. We illustrate the use of this method on two separate representations the tracked object's position, movement, and size; and the tracked object's binary motion silhouettes.
使用基于时间的共现自动分层分类
虽然跟踪系统不知道它跟踪的任何对象的身份,但整个跟踪序列的身份保持不变。我们的系统通过使用序列中表示的累积联合并发来利用这些信息,从而创建表示的分层二叉树分类器。这个分类器对于分类序列和单个实例都很有用。我们在跟踪对象的位置、运动和大小两个单独的表示上说明了这种方法的使用;以及被跟踪物体的二进制运动轮廓。
