Abstract :
This live demonstration is related to ISCAS track “Imagers and Vision Processing”. It showcases the Gaussian pyramid with a CMOS vision sensor with a 176 × 120 pixel array in standard 0.18 μm CMOS technology. The sensing elements are 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.
