Recursive soft morphological filters
Frank Y. Shih, Padmaja Puttagunta · IEEE Transactions on Image Processing · 1995
We present properties of recursive soft morphological filters that use previously filtered outputs as their inputs, cascade combinations of these filters, and the idempotent recursive soft morphological filters. The development allows problems in the implementation of cascaded recursive soft morphological filters to be reduced to the equivalent problems of a single recursive standard morphological filter.
