Pixel-parallel directional state-propagation algorithm for subjective contour generation and its LSI implementation
-
An image processor LSI chip that performs directional pixel-state propagation
processing has been developed using a PWM-based pixel-parallel
architecture. This processing can be used for subjective
contour generation, which is a typical function of the visual system in the human
brain to complete the lacked natural-image information.
The LSI chip has been designed and fabricated using a 0.25 micron mixed-signal CMOS process.
The number of processing units included in the chip is 35x35.
We have verified the propagation process by measuring the fabricated chip,
and have successfully
generated subjective contours of Kanizsa figures using the chip.
