| Abstract: |
| We randomly extracted the feature of local binary patterns(LBP) with different sizes within both positive samples and negative samples.The high-dimensional feature information was projected onto the low rank compression domain based on which the characterization model was established.Then,it compressed samples of foreground and the background targets by using the same random sparse measurement matrix.Finally,the tracking task was formulated as a binary classification via a Naive Bayes classifier.The experiment showed that the proposed method could track the target quickly and constantly.Furthermore,it could also solve the problem of multi-scale change and occlusion issue at the same time. |
