AUTOMATED QUANTIFICATION AND CLASSIFICATION OF MALARIA PARASITES IN THIN BLOOD SMEARS

Malaria is one of the life threatening diseases caused by mosquitoes of Anopheles genus that carries the plasmodium parasite. In recent practice, popular methods of malaria disease identification are based on parasitological testing and diagnosis based on symptoms. Both methods have several drawback...
