optical flow eyeballs
May 23rd, 2009, 10:38pm  
Hey all, just a quick query,
                                         I'm working on a project now that involves optical flow and motion tracking, there's a layered graphic with multiple instances of eyeball images that I have to track for them to follow the direction of movement in a captured image. I thought that using optical flow would be the best solution for something like this, but I need to create an irregular grid for the tracking, constrain them to the area of the eyeballs themselves, and then bound them inside the radius of the image of the eyeball, anything I should keep in mind doing this? What would be the best method of doing it?

Hi there,

I have worked on a very similar project in the past.

...

My project involved eyeballs being projected on a semi-transparent foil onto shop windows. Since the webcam responsible for motion tracking was looking at the projected image, I needed to create 'ignore areas' for the webcam input.

I have used the JMyron library for blob detection, so no optical flow was used. The JMyron library was ideal for me since I could capture webcam, modify the webcam image to create 'ignore areas', and then derive physical locations of people walking in front of the installation through the blob detection supplied by the library.

For an example, check the video of this installation.
You can also see photo's of different results.

Feel free to contact me if you have questions.
