[3D Scan and Print] Paintings!

I made a super-high resolution 3-D scanner for paintings. With that, we scanned two paintings by Rembrandts and a Van Gogh. In order to visualize the result, these were 3-D printed in full color...

[Matlab] Hyperspectral Data To RGB

In here I will describe how you can convert your hyperspectral data containg wavelengths and reflectance values, from for example a hyperspectral cube (or hypercube), to RGB data (or XYZ, Lab, whatever). In order...

[Imaging] Lytro In Matlab

This post tells you how to use images and pictures shot by the Lytro camera with Matlab. Lytro images are called “light field images” or dynamic images are whatever, but whatever they tell you;...

[3D Matlab] Save Stereo 3D image

So if you happen to have a stereo-vision enabled computer, you’d like to look at some 3D stuff. Particularly interesting is of course your own data. Matlab is easy for data processing and making...

[Compass] Easy Magnetometer Calibration

This code is a short example on how to calibrate your cheap magnetic compass. I used a three axis HCM5883 magnetometer from Honeywell. It’s very cheap, but mine was pretty bad. It turned out...

[2D] Optical flow

[2D] Optical flow

This is a function for optical flow in Matlab, using Lucan-kanande/Horn-Schunck optical flow estimation. It includes a sample code and the function itself. Assumptions behind the Lucas-Kanade and Horn-Schunck Optical Flow Estimation methods Both...
