GSANet: Semantic Segmentation with Global and Selective Attention

no code implementations • 14 Feb 2020 • Qing-Feng Liu, Mostafa El-Khamy, Dongwoon Bai, Jungwon Lee

The proposed Global and Selective Attention Network (GSANet) features Atrous Spatial Pyramid Pooling (ASPP) with a novel sparsemax global attention and a novel selective attention that deploys a condensation and diffusion mechanism to aggregate the multi-scale contextual information from the extracted deep features.

DVIO: Depth aided visual inertial odometry for RGBD sensors

no code implementations • 20 Oct 2021 • Abhishek Tyagi, Yangwen Liang, Shuangquan Wang, Dongwoon Bai

Specifically, we propose methods to use the depth measurement using one-dimensional (1D) feature parameterization as well as three-dimensional (3D) feature parameterization.
