Three-Dimensional Multiobject Tracking Based on Voxel Masking Encoder and Deep Hashing Paradigm

This paper presents a new system for 3-D multiobject tracking (MOT, a technique where AI follows multiple objects moving through 3-D space) used in autonomous vehicles to improve safety. The system uses a voxel masking encoder (a method that processes 3-D space divided into small cubes, focusing on important features while ignoring empty space) and deep hashing (a technique that converts objects into compact numerical codes for fast comparison) to better track distant objects, partially hidden objects, and similar-looking objects. The method was tested on the KITTI dataset (a standard collection of driving videos used to evaluate autonomous vehicle systems) and showed better tracking accuracy than existing methods.
