I was messing with webcam and processing this evening, and found that Andy Best has created an amazingly easy and effective visualization of real-time video using processing. He was inspired by computer-generated music video Houses of Cards of Radiohead (Yes, you can watch the video and download the data at google code). I modified his code a bit and captured this,
And I tried with film poster of Coffee and Cigarettes, and generated this,
where the original poster looks like this (you may download the pdf version),
The key to this visualization is fairly simple, “I take the intensity of the pixels from the image and use them as a Z-value for the horizontal lines that I draw. Simple, but I feel that it is pretty effective, especially when the lighting is right.” I guess Jim Jarmush never realized that b&w films could be a great source for visualization.

The only thing I understand is the Z-value…Cuz I see it in papers often…
processing好强大..
