The median filter is a nonlinear image processing operation used to remove impulsive noise from images. An SRAM-based FPGA implementation of this filter speeds up the algorithm, however, configuration memory bit flips induced by single event upsets (SEUs) can cause filter malfunctions. As a result, some pixels can be corrupted. In this paper, a novel technique to protect median filters against SEUs...
In many applications, there is a need to identify to which of a group of sets an element $x$<alternatives><inline-graphic xlink:type="simple" xlink:href="reviriego-ieq1-2535286.gif"/></alternatives> belongs, if any.
