Abstract:A kernel-based metric measuring tracking reliability that is based on discriminative components of a kernel target model and kernel mutual information is presented. The discriminative components of the kernel target model are selected by computing the log-likelihood ratios of classconditional sample densities of these components from a target region and background sampled region. The components selection process is embedded in a metric with kernel mutual information of the target regions of the initial frame a… Show more
“…We place a one-dimensional kernel centered on u and kernel values are used as p(v|u). Gaussian kernel is utilized here, and the conditional probability is given as follows [26]:…”
