OpenCV for Pure Data

Part of the OpenCV functions are now available in Pure Data as extra libraries for the PDP and GEM. The software page is here.

OpenCV 1.2

I just found the new OpenCV 1.2 is out now. The windows installer is available. Let’s try it out.

Augmented Reality Tracking without Marker

Here is a test with the OpenCV SURF sample adapted to a live camera video stream.

Face Detection with Ogre3D

This is a very crude demonstration of integrating the OpenCV face detection facility into Ogre3D. The face location is used to place the sample facial mesh in Ogre3D.

Face Detection Library updated

The face detection library is updated according to the new Processing library requirements. Enjoy coding in the new year.

More OpenCV Book

This is another OpenCV book in Chinese. It has more discussion on 3D vision than the previous one I posted.

Comparison of image processing tools – 4

The next test is to access each pixel in a bitmap and implement a very simple inverse filter. The image has three channels, red, green and blue and each has a resolution of 8 bits.

Test 1
Flash 8

import flash.display.BitmapData;
var bm:BitmapData = new BitmapData(Stage.width,
Stage.height, false, 0xFF000000);
var mc1:MovieClip = this.createEmptyMovieClip(”mc1″,
this.getNextHighestDepth());
var mc2:MovieClip = [...]
