Abstract:
It is presented in this thesis the implementation and definition of a hardware
system for extraction of objects from images with static and non-homogeneous
backgrounds in real time, robust with respect to minor global and local brightness
variations.
The object extraction system was implemented on the GPIP01 (General Purpose
Image Processor) platform designed by Andre Printes. Little modifications on the
platform were done for the implementation of the system.
The object extraction system was submitted to actual environment situations to
test the performance of the extraction method implemented in hardware. The results of
the tests and evaluation of the system demonstrate its capability to extract object from
non-homogeneous backgrounds, to deal with differences between background objects
and foregrounds objects with the same color and its tolerance to brightness variations
and shadows in the background.
