Class VectorVisualLocationFilter

java.lang.Object

org.jactr.modules.pm.visual.memory.impl.filter.AbstractVisualLocationIndexFilter<java.lang.Double>

org.jactr.modules.pm.visual.memory.impl.filter.VectorVisualLocationFilter

All Implemented Interfaces:

IIndexFilter

public class VectorVisualLocationFilter
extends AbstractVisualLocationIndexFilter<java.lang.Double>

enables search along a path defined by one visual-location, an angle (from vertical, -PI - PI), and a threshold. The filter will prioritize visual-location candidates based on their distance from the line defined by visual-location and angle, culling any of those beyond the threshold.
