A low-complexity and low power median filter design
Takeaki Matsubara, Vasily G. Moshnyaga, Koji Hashimoto · 2010
This paper presents a new design of 2D median filter. The filter implements a simple conditional filtering technique that executes fewer computations than related formulations while achieving superior image quality. Experimental FPGA implementations of the proposed filtering scheme for window sizes of (3×3) and (5×5) are very compact, fast and consume low-power.
