ECSIC: Epipolar Cross Attention for Stereo Image Compression

1 code implementation18 Jul 2023 Matthias Wödlinger, Jan Kotera, Manuel Keglevic, Jan Xu, Robert Sablatnig

Our proposed method compresses the left and right images in a joint manner by exploiting the mutual information between the images of the stereo image pair using a novel stereo cross attention (SCA) module and two stereo context modules.

SASIC: Stereo Image Compression With Latent Shifts and Stereo Attention

1 code implementation CVPR 2022 Matthias Wödlinger, Jan Kotera, Jan Xu, Robert Sablatnig

We propose a learned method for stereo image compression that leverages the similarity of the left and right images in a stereo pair due to overlapping fields of view.

Sub-frame Appearance and 6D Pose Estimation of Fast Moving Objects

2 code implementations CVPR 2020 Denys Rozumnyi, Jan Kotera, Filip Sroubek, Jiri Matas

We propose a novel method that tracks fast moving objects, mainly non-uniform spherical, in full 6 degrees of freedom, estimating simultaneously their 3D motion trajectory, 3D pose and object appearance changes with a time step that is a fraction of the video frame exposure time.

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.

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.

The World of Fast Moving Objects

3 code implementations CVPR 2017 Denys Rozumnyi, Jan Kotera, Filip Sroubek, Lukas Novotny, Jiri Matas

The notion of a Fast Moving Object (FMO), i. e. an object that moves over a distance exceeding its size within the exposure time, is introduced.
