Overview with the most useful keyboard shortcuts for After Effects CS4 (Mac OS).
Combination of Frame Differencing and hitTest in as3. Inspired by the Processing sketch of Andy Best where you can pop bubbles if there is movement. By checking the difference between two frames (current and the previous one) we know where there was movement. The movement is stored in a bitmap and with that we can … Read more
Flickr to polaroid style picture stream in Quartz Composer.
Arduino library to control an RGB led with Hue, Saturation and Brigthness values.
If you want to use sensor data in your application you probably want to map the values to a different range. Below a visualisation of the formula that you can use for that.
QRreader example that uses the QR Code Reader by Logosware (libspark project). Code is improved with Adaptive Threshold (by Quasimondo) and other small modifications to improve the QRcode detection.
In the MediaLAB Amsterdam (Lab of the Applied University of Amsterdam) I’ve supervised a few project teams to help them find the right technical solutions for their projects. I’d like to highlight two of them.
Example how to setup serial communication between Flash and Arduino in combination with the Messenger library for Arduino. This is usefull if you want to use Arduino in a different way than as a sensorbox (if you want that check out the As3glue Firmata combination in my other post).
Control parameters in Unity with sensors connected to the Arduino and control actuators connected to Arduino from Unity.
In this ‘Computer Vision’ article you can read about Blob detection and Face detection. I’ve included some video’s to give you an idea about the techniques and links to the most relevant code examples.
