P‐57: A Local Histogram Framework for Contrast Enhancement

Abstract

This paper proposes an implementation framework based on local contrast enhancement (LCE). The framework, implemented on Xilinx Kintex‐7 FPGA platform, is lighted on the 55″ Ultra‐High Definition (UHD) LCD panel and shows the result of image contrast enhancement. In accordance with the hardware design concept, the implementation framework adopts the module partition, hardware parallel processing structure and pipeline processing architecture. The hardware implementation fully achieves the real‐time requirements.
