Real-time detection of moving objects involves memorisation of features inthe template image and their comparison with those in the test image. At highsampling rates, such techniques face the problems of high algorithmiccomplexity and component delays. We present a new resistive switching basedthreshold logic cell which encodes the pixels of a template image. The cellcomprises a voltage divider circuit that programs the resistances of thememristors arranged in a single node threshold logic network and the output isencoded as a binary value using a CMOS inverter gate. When a test image isapplied to the template-programmed cell, a mismatch in the respective pixels isseen as a change in the output voltage of the cell. The proposed cell whencompared with CMOS equivalent implementation shows improved performance inarea, leakage power, power dissipation and delay.
