The effect of illumination compensation methods with histogram back projection for camshift application

Abstract

This paper presents the results of a factorial experiment performed to determine the effect of
illumination compensation methods with histogram back projection to be used for object
tracking algorithm continuous adaptive mean-shift (Camshift). Since Camshift tracking can be
used for distance approximation of an object, a precise tracker algorithm is required. This
study compared two types of illumination compensation methods using Design of Experiment
(DOE) in the presence of illumination inconsistency. Based on the results, it was found that
selecting two channels as reference in histogram back projection weakens the accuracy of
Camshift tracking whereas the combination of both methods produces results that are more
desirable.
