Live Demonstration: Gaussian Pyramid Extraction with a CMOS Vision Sensor
This live demonstration showcases the Gaussian pyramid with a CMOS vision sensor. The chip features a 176 $\times$ 120 pixel array in standard 0.18 $\mu$m CMOS technology. The sensing elements are 3-Transistor Active Pixel Sensors (3T-APS) with in-pixel ADC and CDS. The Gaussian pyramid is extracted concurrently with a double-Euler switched-capacitor network on the same substrate, giving RMSE errors below 1.2\% of FSO. The chip provides a Gaussian pyramid of 3 octaves with 6 scales each with an energy cost of 26.5 nJ/px at 2.64 Mpx/s.
