Moving Shadow Removal for Multi-Objects Tracking in Outdoor Environments

Abstract
Shadow detection and removal has had great interest in
computer vision especially in outdoor environments. It is an
important task for visual tracking, object recognition, and
many other important applications. One of the fundamental
challenges for accurate tracking is achieving invariance to
shadows. Two or more separate objects can appear to be
connected through shadows. Many algorithms have been
proposed in the literature that deal with shadows. However,
the problem remains largely unsolved and needs further
research effort.
This paper proposes a method for removing cast shadows
from vehicles in outdoor environments. The proposed method
employs the estimated background model of the video
sequence and applies a Gamma decoding followed by a
thresholding operation. Experimental results show the success
of the proposed method in detecting and removing shadows
robustly and leads to considerable improvements in multiple
object tracking.
