'**SUMMARY**
Given a point (default to center of the image), return the euclidean distance of x,y from this point'

def distanceFrom(self, point=((-1), (-1))):

    if ((point[0] == (-1)) or (point[1] == (-1))):
        point = (np.array(self.image.size()) / 2)
    return spsd.euclidean(point, [self.x, self.y])
