Design of a real time system for nonlinear enhancement of video streams by an integrated neighborhood dependent approach

摘要

In this paper, we propose an efficient VLSI architecture for real time enhancement of video containing non-uniform and low light conditions. The nonlinear transfer function is determined by the cumulative distribution function of the previous frame. A dataflow design technique is used to construct a pipelined multimodule architecture. The design is capable of processing 73 1024/spl times/1024 video frames per second.
