Vision-based Uneven BEV Representation Learning with Polar Rasterization and Surface Estimation

CoRL 2022poster

In this work, we propose PolarBEV for vision-based uneven BEV representation learning. To adapt to the foreshortening effect of camera imaging, we rasterize the BEV space both angularly and radially, and introduce polar embedding decomposition to model the associations among polar grids. Polar gri…

Deep Online Correction for Monocular Visual Odometry

ICRA 2021poster

In this work, we propose a novel deep online correction (DOC) framework for monocular visual odometry. The whole pipeline has two stages: First, depth maps and initial poses are obtained from convolutional neural networks (CNNs) trained in self-supervised manners. Second, the poses predicted by CNNs…

The Discrete Stockwell Transforms for Infinite-Length Signals and Their Real-Time Implementations

ICASSP 2020accepted

The various forms of the Stockwell transforms (ST) introduced in the literature have been developed for off-line signal processing on finite-length signals. However, in many applications such as audio, medical or radar signal processing, signals to be analyzed are of large sizes or received in real-…
