Median and morphological filters based on LCBP rank filter
Dragana Z. Prokin, Milan D. Prokin · 2012
The presented median and morphological (min and max) filters based on low complexity bit-pipeline (LCBP) rank filter have reduced complexity of specialized processing hardware, due to similar pipeline stages and the complete absence of sorting networks in comparison with other solutions. FPGA realization of bit-pipeline median and morphological filter according to this paper provides significantly higher maximum operating frequency and much smaller used chip resources in comparison with often recommended state-of-the-art sorting methods.
