HoughEyeTracker(AEChip chip)
Creates a new instance of TypeCoincidenceFilter |
Method Summary | |
---|---|
void |
annotate(float[][][] frame)
annotate the RGB frame somehow by color pixels in the rendered pixel frame data. |
void |
annotate(javax.media.opengl.GLAutoDrawable drawable)
Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). |
void |
annotate(java.awt.Graphics2D g)
each annotator is called by the relevant class (e.g. |
EventPacket |
filterPacket(EventPacket in)
Subclasses implement this method to define custom processing. |
