Der Code dort oben kommt auf 10 fps. Problem ist, das Durchlaufen durch die "contour" (Liste).

Code:
     while contour:

                bound_rect = cv.BoundingRect(list(contour))
                contour = contour.h_next()

                pt1 = (bound_rect[0], bound_rect[1])
                pt2 = (bound_rect[0] + bound_rect[2], bound_rect[1] + bound_rect[3])
                points.append(pt1)
                points.append(pt2)
                centroidx=cv.Round((pt1[0]+pt2[0])/2)
                centroidy=cv.Round((pt1[1]+pt2[1])/2)
                centroid = (centroidx, centroidy)
            if len(points):
                radius = abs(pt1[0]-pt2[0])/2 
                if True: #radius > 2 and radius != 159:
                    self.centroid = centroid
                    self.radius = radius
                    if self.gui is True:
                        cv.Circle(color_image, centroid , radius , cv.CV_RGB(255,0,0), 1)
                        cv.Rectangle(color_image, pt1, pt2, cv.CV_RGB(255,0,0), 1)
                        cv.PutText(color_image, str(centroid)+" r="+str(radius), centroid, cv.InitFont(cv.CV_FONT_HERSHEY_SIMPLEX, 1, 1, 0, 2, 1), cv.CV_RGB(255,0,0))
#                    print str(centroid)+" r="+str(radius)
                else:
                    self.centroid = None
                    self.radius = None
