Abstract:
The objective of this work is to compare the results of the classical identification of diatoms by optical microscope to the automatic identification of the diatoms. For the first method, we determined the diatoms using an optical microscope and the identification keys. Concerning the second method, we relied on the processing and analysis of the images to automatically recognize a diatom. Our aim is to compare the results of the manual identification of diatoms with the results of the automatic identification of the same sample. The purpose of this comparison is to verify whether the automaticanalysis can give acceptable results in order to replace the manual determination. We used the Image j software for the development of our program and based on the notion of points of interest and the freeman code. The results of the determination of the diatoms by optical microscope which lasted more than one month did not exceed 92% (for 104 species of diatoms 96 species were identified), whereasthe automatic identificationrequires only a few seconds, with much better results (97%).
