You could check my PhotoSqueak project, at

eProcessing.html

In PhotoSqueak I defined new classes for images, that
support different pixel types (1 byte, long int and float),
and different color band count (you can work in images with
more or less than 3 color bands). So, I implemented all the
algorithms in those classes. This is more powerful, but
less integrated with the rest of the system. I also
implemented some operations in Slang, and VM plugin can be
generated, giving C performance and Smalltalk ease. I'm
taking a second course on Image Processing at the
university, and will publish the outcome when ready.
