Hey, i have a video (pretty static, though there are a few points that change) that i would like to be able to see if certain points in the video are a certain color.

If you have seen the YouTube video of "Gumball Sequencer" this is the idea i want to try to emulate.

I am trying to use the suckah object, and it does exactly what i want it to when i position suckah behind my jit.pwindow and click on the window...but when i try to feed it a set of packed coordinates, it doesnt seem to get me the right information out of suckah. is there an object that i could send either one coordinate pair or a list of coordinate pairs to the jit.pwindow to get the color of certain pixels? or a group of pixels around a center point?

And i have looked at the cv.jit externals...cool, but i dont think anything there will help me

How about using the mouse coord output from jit.pwindow to query the
matrix you're inputting?

Ya, thats what im asking, how can i query the matrix by giving it coordinates?

Ok, sorry - i have not really ever used jit before, so how do i get my video into the matrix? and then specifically how do i send coordinates using getcell

Please read the first few Jitter tutorials, and then post back if you

Please read the first few Jitter tutorials, and then post back if you  
still have questions.

ok, im getting stuff with the getcell in the jit.matrix, however, it doesnt seem to be right. i send a packed message of x-coord, y-coord to "getcell $1" and that goes to the matrix...but no matter what the x and y coordinates are, the value that comes out of the matrix is the same.

i attached a newer version of my patch...can you let me know what i am doing incorrectly?

look at the right outlet of the jit.matrix object when you send that
