How would I convert jit.lcd 4 char 600 400 as a matrix that can be tracked with cv.jit.track. As of right now I get the error message :mismatch plane. Basically I am trying to track movement of changing graphics from the jit.lcd.

I am new to jitter.

The cv.jit objects nearly all work on a 1 plane incoming image. Kind of quirky how jit.lcd only works on 4 plane, but you can use a jit.rgb2luma object to convert the stream.

hmm I had jit.rgb2luma and it still gave me this error (see attached image)

can you post a copy-compressed patch? I don't know how to get that error.

tyring to modify Lsystem Garden.maxpat

You should be able to just patch from the output of the jit.lcd into the rgb2luma like so. Is it not working for you?

maybe the thing you're getting is that the l system doesn't draw over the 0. 0. area of the image? The cv.jit.track will only look right where the point already is. I made a quick thing using cv.jit.blobs.centroids to pick the starting point:
