MGTANet: Encoding Sequential LiDAR Points Using Long Short-Term Motion-Guided Temporal Attention for 3D Object Detection

1 code implementation1 Dec 2022 Junho Koh, Junhyung Lee, Youngwoo Lee, Jaekyum Kim, Jun Won Choi

While conventional 3D object detectors use a set of unordered LiDAR points acquired over a fixed time interval, recent studies have revealed that substantial performance improvement can be achieved by exploiting the spatio-temporal context present in a sequence of LiDAR point sets.

Joint 3D Object Detection and Tracking Using Spatio-Temporal Representation of Camera Image and LiDAR Point Clouds

no code implementations14 Dec 2021 Junho Koh, Jaekyum Kim, Jinhyuk Yoo, Yecheol Kim, Jun Won Choi

The detector constructs the spatio-temporal features via the weighted temporal aggregation of the spatial features obtained by the camera and LiDAR fusion.

Joint Representation of Temporal Image Sequences and Object Motion for Video Object Detection

1 code implementation20 Nov 2020 Junho Koh, Jaekyum Kim, Younji Shin, Byeongwon Lee, Seungji Yang, Jun Won Choi

In this paper, we propose a new video object detector (VoD) method referred to as temporal feature aggregation and motion-aware VoD (TM-VoD), which produces a joint representation of temporal image sequences and object motion.

Probabilistic Vehicle Trajectory Prediction over Occupancy Grid Map via Recurrent Neural Network

no code implementations24 Apr 2017 ByeoungDo Kim, Chang Mook Kang, Seung Hi Lee, Hyunmin Chae, Jaekyum Kim, Chung Choo Chung, Jun Won Choi

Our approach is data-driven and simple to use in that it learns complex behavior of the vehicles from the massive amount of trajectory data through deep neural network model.
