Abstract

Malaria is a parasitic disease caused by the bite of infected Anopheles mosquitoes. The infection is caused by Plasmodium parasites transferred through the mosquitoes bite. Currently the diagnosis system is performed manually by experts through observation of blood smears under microscope. This diagnostic system is prone to human error and very subjective. This project presents the development of a software module to automatically identify Plasmodium Vivax (PV) in trophozoite stage using morphological techniques. 350 PV images are taken using a video camera with 1000x magnification that is attached to a microscope. An automated system to detect PV in thin blood smear images is created using Matlab 2013a image processing toolbox. The thin blood smear images will undergo pre-processing, segmentation and classification stages. This system will focus on morphological techniques of dilation, erosion and hole filling during the segmentation and the morphological hit-miss of area for the classification stage. The process will classify the parasite in trophozoite stage. 100 images are used for calculating the parasite area while 250 images are used for final testing in detecting the parasite. The system produces 98.8% sensitivity, 99.90% accuracy and 99.96% specificity. The diagnosis time for one image is 0.2 seconds and 2 seconds for 25 images in one run. The result had shown that the system is able to correctly classify the trophozoite parasites in the PV images in very short time. With a reliable system, the time taken to diagnose malaria parasite can be reduced and thus improves the current diagnosis process.
