Fig. 1From: Towards a needle-free diagnosis of malaria: in vivo identification and classification of red and white blood cells containing haemozoinBlood smear image analysis. Images of thin-film blood smears containing a Plasmodium falciparum iRBC (top row) and a pWBC (bottom row), both surrounded by uninfected RBCs. Brightfield images were collected under narrowband illumination (λ = 655 nm ± 20 nm). Cells were segmented using the brightfield image. An intensity threshold was applied to isolate the haemozoin absorbance signal. DAPI staining was used to identify cell typeBack to article page
