GP-S3Net: Graph-based Panoptic Sparse Semantic Segmentation Network

no code implementations ICCV 2021 Ryan Razani, Ran Cheng, Enxu Li, Ehsan Taghavi, Yuan Ren, Liu Bingbing

GP-S3Net is a proposal-free approach in which no object proposals are needed to identify the objects in contrast to conventional two-stage panoptic systems, where a detection network is incorporated for capturing instance information.

(AF)2-S3Net: Attentive Feature Fusion with Adaptive Feature Selection for Sparse Semantic Segmentation Network

no code implementations8 Feb 2021 Ran Cheng, Ryan Razani, Ehsan Taghavi, Enxu Li, Bingbing Liu

Autonomous robotic systems and self driving cars rely on accurate perception of their surroundings as the safety of the passengers and pedestrians is the top priority.

Adaptive Hierarchical Down-Sampling for Point Cloud Classification

no code implementations CVPR 2020 Ehsan Nezhadarya, Ehsan Taghavi, Ryan Razani, Bingbing Liu, Jun Luo

While several convolution-like operators have recently been proposed for extracting features out of point clouds, down-sampling an unordered point cloud in a deep neural network has not been rigorously studied.
