Joint 3D Layout and Depth Prediction from a Single Indoor Panorama Image

no code implementations ECCV 2020 Wei Zeng, Sezer Karaoglu, Theo Gevers

Leveraging the layout depth map as an intermediate representation, our proposed method outperforms existing methods for both panorama layout prediction and depth estimation.

Multi-Loss Weighting with Coefficient of Variations

1 code implementation3 Sep 2020 Rick Groenendijk, Sezer Karaoglu, Theo Gevers, Thomas Mensink

In this paper, we propose a weighting scheme based on the coefficient of variations and set the weights based on properties observed while training the model.

Kinship Identification through Joint Learning Using Kinship Verification Ensembles

1 code implementation ECCV 2020 Wei Wang, ShaoDi You, Sezer Karaoglu, Theo Gevers

The experiments further show significant performance improvement of kinship verification when trained on the same dataset with more realistic distributions.

On the Benefit of Adversarial Training for Monocular Depth Estimation

1 code implementation29 Oct 2019 Rick Groenendijk, Sezer Karaoglu, Theo Gevers, Thomas Mensink

For the quality of the image reconstruction and disparity prediction, a combination of different losses is used, including L1 image reconstruction losses and left-right disparity smoothness.

Detect2Rank : Combining Object Detectors Using Learning to Rank

no code implementations26 Dec 2014 Sezer Karaoglu, Yang Liu, Theo Gevers

Experiments on the PASCAL VOC07 and VOC10 datasets show that the proposed method significantly outperforms single object detectors, DPM (8. 4%), CN (6. 8%) and EES (17. 0%) on VOC07 and DPM (6. 5%), CN (5. 5%) and EES (16. 2%) on VOC10.
