Differential Analysis of Multispectral Images for Terrain Identification
Omar Kashmar, Hemendra Arya, Fulvio Mastrogiovanni
Reliable terrain understanding is a prerequisite for autonomous robot navigation. Yet, the widespread RGB-based perception can fail under low illumination, shadows, and material ambiguities. In this work we propose DRIFT, a lightweight multispectral framework that combines raw sp…
