Paper Abstract

Many vision tasks can be posed as Bayesian inference, and the entropy of the posterior probability is a measure for uncertainty of perception, imperceptibility. In this paper, we studied the imperceptibility of multiple object tracking, intrackability. Entropy theory and Bayesian framework are used to represent multiple objects intrackability. Intrackability is computed by different kinds of tracking features. Feature selection is crucial for intrackability computation. An example of umbrellas tracking is shown in this paper. The intrackability which is computed by appearance and shape feature is compared. At last, we use intrackability to guide one application--Automatic grouping. Objects are dynamically merged and tracked as a group when they come close to each other. Automatic grouping reduces the representation when some details can't be perceived. After the intrackable part of the representation is discarded, the computation is reduced.
