Face-TLD: Tracking-Learning-Detection applied to faces
Autor: Kalal, Zdenek; Mikolajczyk, Krystian; Matas, Jiří
(IEEE, 2010-09)A novel system for long-term tracking of a human face in unconstrained videos is built on Tracking-Learning-Detection (TLD) approach. The system extends TLD with the concept of a generic detector and a validator which is ... -
Forward-Backward Error: Automatic Detection of Tracking Failures
Autor: Kalal, Zdenek; Mikolajczyk, Krystian; Matas, Jiří
(IEEE, 2010-08)This paper proposes a novel method for tracking failure detection. The detection is based on the Forward-Backward error, i.e. the tracking is performed forward and backward in time and the discrepancies between these two ... -
Improving Descriptors for Fast Tree Matching by Optimal Linear Projection
Autor: Mikolajczyk, Krystian; Matas, Jiří
(IEEE, 2007-10)In this paper we propose to transform an image descriptor so that nearest neighbor (NN) search for correspondences becomes the optimal matching strategy under the assumption that inter-image deviations of corresponding ... -
Online learning of robust object detectors during unstable tracking
Autor: Kalal, Zdenek; Matas, Jiří; Mikolajczyk, Krystian
(IEEE, 2009-09)This work investigates the problem of robust, longterm visual tracking of unknown objects in unconstrained environments. It therefore must cope with frame-cuts, fast camera movements and partial/total object occlusions/d ... -
P-N Learning: Bootstrapping Binary Classifiers by Structural Constraints
Autor: Kalal, Zdenek; Matas, Jiří; Mikolajczyk, Krystian
(IEEE, 2010-06)This paper shows that the performance of a binary classifier can be significantly improved by the processing of structured unlabeled data, i.e. data are structured if knowing the label of one example restricts the labeling ...
