SPRINGERBRIEFS IN COMPUTER SCIENCE ROBUST MOT...

This work proposes a complete sensor-independent visual system that provides robust target
motion detection. First  the way sensors obtain images  in terms of resolution distribution and
pixel neighbourhood  is studied. This allows a spatial analysis of motion to be carried out.
Then  a novel background maintenance approach for robust target motion detection is
implemented. Two different situations are considered: a fixed camera observing a constant
background where objects are moving  and a still camera observing objects in movement within a
dynamic background. This distinction lies on developing a surveillance mechanism without the
constraint of observing a scene free of foreground elements for several seconds when a reliable
initial background model is obtained  as that situation cannot be guaranteed when a robotic
system works in an unknown environment. Other problems are also addressed to successfully deal
with changes in illumination  and the distinction between foreground and background elements.
