Impact of Analog Memories Non-Idealities on the Performance of Foreground Detection Algorithms

The high number of memory accesses in background subtraction algorithms constraints the choice of the memory topology of an analog implementation of a hardware-oriented version of the well-known PBAS algorithm (HO-PBAS). As the first step towards the implementation of a CMOS vision chip with per-pixel processing to run the HO-PBAS, this work assesses the impact of the circuit non-idealities of the three main analog memory topologies into the segmentation result on the CDNET database.
