“Triangular Life”
Recently I looked through a bunch of triangular cellular automata in which each (1) uses two states, (2) uses the simple alive cell count type of rule, and (3) uses the neighborhood around a cell…
Basic signals & slots in C++
I put up some code on github that implements basic signals and slots functionality using standards compliant C++. It’s one header file “signals.hpp”. See here: link to github This implementation of signals is a re-work…
RIP Magnus Wenninger
Father Magnus Wenninger died last month.
I put pypacker up on github
Probably the most read post on this blog is about sprite packing in Python, here. At the time I didn’t have a github account and was planning to make a small desktop application out of…
Mean Shift Segmentation in OpenCV
I’ve posted a new repository on GitHub for doing mean shift segmentation in C++ using OpenCV: see here. OpenCV contains a mean shift filtering function and has a GPU, I think CUDA, implementation of mean…
Floodfilling in OpenCV with multiple seeds
One irritating thing about OpenCV is that as a computer vision library it doesn’t actually offer a lot of routines for dealing with connected components easily and efficiently. There’s cv::findContours and two versions of cv::connectedComponents…
