  Field Programmable Gate Array (FPGA) technology has gained vital importance
mainly because of its parallel processing hardware which makes it ideal for
image and video processing. In this paper, a step by step approach to apply a
linear spatial filter on real time video frame sent by Omnivision OV7670 camera
using Zynq Evaluation and Development board based on Xilinx XC7Z020 has been
discussed. Face detection application was chosen to explain above procedure.
This procedure is applicable to most of the complex image processing algorithms
which needs to be implemented using FPGA.
