1. Hilbert curve indexing

    Recently I wanted to generate hilbert curve indexing of 2D array as a part of one experiment. The experiment wasn't very successful itself, but I found the resulting Python code for curve generation prety neat to post it.

    Here are a couple of interesting references on space-filling curve construction ...

  2. Geodesic distance transform

    This notebook shows how Geodesic Discance Transform (GDT) using Fast Sweeping Method (FSM) can be implemented using Python. GDT can be thought of as a computation of shortest pathes on an image plane with a given cost function. It can be used as a part of more complex image processing ...

  3. Kinect + PS3 Move

    Once I happened to have both MS Kinect and PS3 Move on my table. I connected both of them to my PC (trivial for Kinect and ugly for Move). Then I tried to calibrate both cameras to match their coordinate frames. Here is the result I managed to get:

  4. Coral growth (and voxels)

    Before I learned about computer vision my main interests where computer graphics and computational modeling of physical and biological systems. At the time I was playing with voxel graphics I wanted to find a source of interesting, complex and natural-looking geometry. My adviser pointed me to the work Roeland Merks ... read more

  5. Plane tracking with Python OpenCV

    When I was working Python samples for OpenCV I decided to try to reproduce this real-time plane tracking demo using Features2D framework. Here is a couple of videos showing the results:



    I use ORB feature detector/descriptor and FLANN-based descriptor matcher. Also cv2.solvePnP function is used to estimate camera ...

  6. My first youtube video

    In a year 2007 I was doing a small course project on cellular automaton simulation of physical phenomena. I was intrigued by the simplicity of Lattice-Gas model and its ability to capture the complex stuff that happens in fluid flows:

    "We have noticed in nature that the behavior of a ...
