DiffSF: Diffusion Models for Scene Flow Estimation

1 code implementation8 Mar 2024 Yushan Zhang, Bastian Wandt, Maria Magnusson, Michael Felsberg

Aiming at improving accuracy while additionally providing an estimate for uncertainty, we propose DiffSF that combines transformer-based scene flow estimation with denoising diffusion models.

High-fidelity Pseudo-labels for Boosting Weakly-Supervised Segmentation

1 code implementation5 Apr 2023 Arvi Jonnarth, Yushan Zhang, Michael Felsberg

Our work is based on two techniques for improving CAMs; importance sampling, which is a substitute for GAP, and the feature similarity loss, which utilizes a heuristic that object contours almost always align with color edges in images.

Flow-guided Semi-supervised Video Object Segmentation

no code implementations25 Jan 2023 Yushan Zhang, Andreas Robinson, Maria Magnusson, Michael Felsberg

A model to extract the combined information from optical flow and the image is proposed, which is then used as input to the target model and the decoder network.

A Machine Learning Framework to Forecast Wave Conditions

1 code implementation25 Sep 2017 Scott C. James, Yushan Zhang, Fearghal O'Donncha

These input data along with model outputs of spatially variable wave heights and characteristic period were aggregated into supervised learning training and test data sets, which were supplied to machine learning models.
