Figure 2From: A morphometric and histological study of placental malaria shows significant changes to villous architecture in both Plasmodium falciparum and Plasmodium vivax infectionImage processing steps used to generate quantitative outputs from haematoxyling and eosin-stained placental sections. The various stages of processing are graphically illustrated in the following sequence: (A) original image (magnification x400); (B) preprocessing step following removal of partial outlines and non-terminal villi; (C) adjusted threshold to generate solid red pixelated areas; (D) computerized measurement of area of terminal villi using the resultant outlines.Back to article page
