Detection Is Tracking: Point Cloud Multi-Sweep Deep Learning Models Revisited

no code implementations24 Feb 2024 Lingji Chen

In applications such as autonomous driving, lidar measurements in the form of point clouds are usually passed through a "virtual sensor" realized by a deep learning model, to produce "measurements" such as bounding boxes, which are in turn ingested by a tracking module to produce object tracks.

How to Backpropagate through Hungarian in Your DETR?

no code implementations12 Nov 2022 Lingji Chen, Alok Sharma, Chinmay Shirore, Chengjie Zhang, Balarama Raju Buddharaju

The DEtection TRansformer (DETR) approach, which uses a transformer encoder-decoder architecture and a set-based global loss, has become a building block in many transformer based applications.

A Merge/Split Algorithm for Multitarget Tracking Using Generalized Labeled Multi-Bernoulli Filters

no code implementations5 Aug 2019 Lingji Chen

The class of Labeled Random Finite Set filters known as the delta-Generalized Labeled Multi-Bernoulli (dGLMB) filter represents the filtering density as a set of weighted hypotheses, with each hypothesis consisting of a set of labeled tracks, which are in turn pairs of a track label and a track kinematic density.
