Abstract:
This document aims to explain the feasibility of image
processing using GTK, the GIMP Tool Kit, which is a free software
graphics toolkit useful for GUI programming. GTK is also freely
available for the GNU/Linux and many other platforms.
This document however just scratches the surface when it comes to
explaining the nook & corner of Image processing theory. It shows
examples of pixel based filters and convolution filters.
