A window-based image processing is an elementary part of image processing area. Because window-based image processing is computationally intensive and data intensive, it is hard to perform all of the operations of a window-based image processing in real-time by using a software program on general-purpose computers.
This paper proposes a parallel hardware architecture that can perform a window-based image processing in real-time using FPGA (Field Programmable Gate Array). A dynamic threshold circuit and a local histogram equalization circuit of the proposed architecture are designed using VHDL(VHSIC Hardware Description Language) and implemented with an FPGA. The performances of both implementations are measured.
