<p>This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++.

Our main action taken to speed up the program was to use C++ instead of Matlab. It is safe to say that we managed to fulfill our commitments with respect to speed, but we are not completely satisfied with the results regarding the quality. Although the result does not differ a great deal compared to the Matlab version, there are still improvements to make before considering using it commercially. </p><p>Our program is an extension of an existing C++ program, written by Per Fredriksson. We used his program as base to our program. The addition we have made to his code is the possibility to halftone colour images.</p>
