Abstract :
In this paper, a new Cellular Neural Network (CNN) structure for implementing two dimensional Gabor-type filters is proposed over our previous design. The structure is coded in VHDL and realized on a state of the art Altera Stratix IV 230 FPGA. The prototype supports Full-HD 1080p resolution and 60 Hz frame rate. One dedicated processor is used for each Euler iteration, where time step is taken as the same as optimum step size, and 50 iterations are implemented. The input/output, control, RAM and communication blocks of the realization are taken from our second generation real time CNN emulator (RTCNNP-v2).
