示例9: direction
# HARRIS CORNER DETECTION
# corner detection is based upon the change of the position vector with respect
# to arc length.
# approximates the autocorrelation function in the direction (u, v). A measure of
# curvature is given by the minimum value obtained by considering the shifts (u, v)
# in the four main directions. That is, by (1,0), (0,−1), (0,1) and (−1,0). The minimum is chosen
# because it agrees with the following two observations. First, if the pixel is in an edge defining a
# straight line, is small for a shift along the edge and large for a shift perpendicular to
# the edge. In this case, we should choose the small value since the curvature of the edge is small.
# Secondly, if the edge defines a corner, then all the shifts produce a large value. Thus, if we also
# chose the minimum, this value indicates high curvature.
