Abstract :
This paper presents a VLSI architecture of a frame-based adaptive quantization technique based on the fast boundary adaptation rule (FBAR). The adaptive quantization algorithm is integrated together with a 128times128 pixel CMOS image sensor array. The pixel operation is based on biologically inspired time-to-first spike encoding scheme. System and circuit level simulations show the successful operation of the proposed architecture
