We present a number of autofocusing methods in light microscopy for use in diatom identification.
Among these, the Tenengrad method has been considered one of the best. The basic …

An optical–digital system was used to identify five phytoplankton species of the genus
Ceratium from Todos Santos Bay off the California Peninsula, Mexico. The system recognized …
