2017-06-07 13:32:38 -0600 | asked a question | SimpleBlobDetector results: coordinates based on pixel centre or edge? Hi. I'm new to OpenCV, please be gentle. :) What coordinate system are the results of SimpleBlobDetector in? Specifically: are things measured from the centre of a pixel or the edge? My experiments thus far suggest that (0.0, 0.0) is the centre of the top-left pixel, but I'd appreciate confirmation from someone in the know... Thanks, Sean |
