cv.jit.shift extracting co-ordinates

February 7, 2010 | 8:25 pm

I am using cv.jit.shift with CAMSHIFT algorithm for mouth recognition. This allows me to draw a rectangle around the mouth to follow it’s movement. I now need to extract the co-ordinates of each of the 4 points of the rectangle. Does anyone know what object I could use for this?

try this! it’s an excellent starting point. this patch as you’ll see is a mix between to patches so it still has a lot of stuff you probably won’t need… i didn’t have the time to merge them properly and leave just the essentials, but i got a tangible output of the x,y coordinates. this will give you number of blob, x, y and area (i’m using cv.jit.blobs.centroids), but it should be quite easy to use with cv.jit.shift and get the values you need.

hope it helps!


to get it running go to:
download the stuff u don’t have and install it
