This is my first post, I have used the resources quite often, but up until now I have been lucky with searching, but this time I have a problem.
I am trying to take an input from a webcam and do a background subtraction to capture movement. These images (one every second) then need to have a transparency added to them (I have tried alpha and tint). These images then need to be overlayed on one another to capture an hour's worth of movement through a space. This final image will be projected on a wall and change every second as the next second is captured.
What I have so far is the background subtraction and I am running into problems of changing opacity of the images. I am also lost on how to overlay 3600 (1 image per second for 1 hour) of these images. My first thoughts were to save out each image with transparency and then have another sketch pull these image to do the overlay. Can anybody help me with my problem or offer a better way of doing this?
Please forgive me as Processing is not my native tongue, I am an architecture student so I think more through other programs but have enough background with programming/scripting to understand the basics plus some.
