I've been feverishly working on a patch and have hit a brick wall. I am trying to use the x & y values I get from blobs.centroids essentially as a mouse state to draw on an lcd. I have set up the patch to use motion sensing or background subtraction, but once I grab the data from the blobs.centroid, I can't seem to transfer the data into the lcd. Can anyone help me or give any suggestion where to go from here?

is the problem how to get from blobs.centroid (float32 matrix) to LCD coordinates (X Y resolution as integers)? you'll want jit.spill or jit.iter, then grab the points you need, scale them to appropriate values.

If you have more than one blobs.centroids, you'll get X-axis swapping, look to the more recent cv.jit package (cv.jit.touches) to deal with this. if it's just one blob, no worries.
