Non-Causal Tracking by Deblatting

2 code implementations15 Sep 2019 Denys Rozumnyi, Jan Kotera, Filip Šroubek, Jiří Matas

Tracking by Deblatting stands for solving an inverse problem of deblurring and image matting for tracking motion-blurred objects.

Visual Coin-Tracking: Tracking of Planar Double-Sided Objects

no code implementations7 Aug 2019 Jonáš Šerých, Jiří Matas

We introduce a new video analysis problem -- tracking of rigid planar objects in sequences where both their sides are visible.

Intra-frame Object Tracking by Deblatting

3 code implementations9 May 2019 Jan Kotera, Denys Rozumnyi, Filip Šroubek, Jiří Matas

We propose a novel approach called Tracking by Deblatting based on the observation that motion blur is directly related to the intra-frame trajectory of an object.

Leveraging Outdoor Webcams for Local Descriptor Learning

1 code implementation28 Jan 2019 Milan Pultar, Dmytro Mishkin, Jiří Matas

We present AMOS Patches, a large set of image cut-outs, intended primarily for the robustification of trainable local feature descriptors to illumination and appearance changes.

Continual Occlusions and Optical Flow Estimation

no code implementations5 Nov 2018 Michal Neoral, Jan Šochman, Jiří Matas

We show that providing occlusion masks as an additional input to flow estimation improves the standard performance metric by more than 25\% on both KITTI and Sintel.

Now you see me: evaluating performance in long-term visual tracking

no code implementations19 Apr 2018 Alan Lukežič, Luka Čehovin Zajc, Tomáš Vojíř, Jiří Matas, Matej Kristan

We propose a new long-term tracking performance evaluation methodology and present a new challenging dataset of carefully selected sequences with many target disappearances.

Depth Masked Discriminative Correlation Filter

no code implementations26 Feb 2018 Uğur Kart, Joni-Kristian Kämäräinen, Jiří Matas, Lixin Fan, Francesco Cricri

Depth information provides a strong cue for occlusion detection and handling, but has been largely omitted in generic object tracking until recently due to lack of suitable benchmark datasets and applications.

Discriminative Correlation Filter with Channel and Spatial Reliability

3 code implementations CVPR 2017 Alan Lukežič, Tomáš Vojíř, Luka Čehovin, Jiří Matas, Matej Kristan

Short-term tracking is an open and challenging problem for which discriminative correlation filters (DCF) have shown excellent performance.
