Comparative analysis in the implementation of subtraction and thresholding for digital image processing

The aim of this work is to demonstrate the advantages and disadvantages of different ways of implementing subtraction and thresholding in the processing of digital images. The four different systems will be analysed: first in a PC computer with a Borland C++ program, second with an embedded microprocessor programmed in C++, third with a DSP also programmed in C++, and finally with a hardware designed in VHDL.
