For each cell, direction preference is coded by the asymmetry in the line segment flanking the receptive-field center (dot).
Then the second revolute pair of the chain allows it to perform a full rotation of the straight line segment which generates a cylindrical cone.
However, when no corner is detected, the algorithm will return all of the points, whether the feature is a line segment or a circular arc.
For a line segment with end points included we use its closure ab.
The line segment method models grace notes as other slurred notes.
We claim that g(1) = -a0 lies above the l4 line segment.
The vertical line segment is the axis of rotation.
Thus, movements of the sliding joint will generate a straight line segment.
