Hello list
I have to find for an installation the four corners of a bed (a rectangle) seen
from above against the background (the floor), and this bed might slide a bit,
so from time to time update the coordinates of the four corners. A person might
be on the bed or close to it. So the general problem is
find the coordinates x,y in the video frame (GEM) of a nearly
perfect quadrilateral with a rather simple overall visual configuration
Apparently, haarcascade techniques which work fantastically for face / hands
(A.Villeret) seem inappropriate because the rectangle or quadrilateral is a too
simple shape :
anyone has a hint ? any object around ? blob ? boundaries ??
Thanks a lot !
Jean-Marie
