Snow on branches

Today we were in Muenster, Germany. Charming little city!  :)   We took some pics. from the city, but what stole most of my attention were the trees and the snow on them. It has been snowing for quite a while, and the city was just like a xmas postcard.  Here one of the photos I liked the most.  Other photos can be see here.

Art within Interpolations

As it happens many times, I came across a beautiful image during my work. This is the difference between two interpolated CT images using different window functions (Lanczos and Welch) in a Windowed Sinc Interpolator. The cold areas indicate that the 'colors' of the resulting images were almost the same, while warm areas indicate larger differences.  In general you can see a kind of a grid, which is an aliasing effect (at least, that's my theory...).
