Abstract: Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of real time algorithms suited to video image processing applications. The unique architecture of the FPGA has allowed the technology to be used in many applications encompassing all aspects of video image processing. Non-linear morphological filters represent a basic set of image operations for a number of applications. In this work, an implementation of four morphological image filtering techniques using a FPGA Nexus II, Xilinx, Spartan 3E, is presented. The FPGA-based system is accessed through a Mat lab graphical user interface, which handles the communication setup. A comparison between results obtained from MATLAB simulations and the described FPGA-based implementation is presented
