ParasitoBank: Dataset of helminths and protozoa in coprology samples
A dataset of microscopy images for parasite detection in stool samples, containing bounding box annotations for multiple parasite species.
Description
This dataset contains 779 images of the visual field from fresh fecal samples analyzed under the microscope. These images were acquired using a Motorola G84 cellphone at resolutions of 3,072 x 3,072 pixels and 3,072 x 4,080 pixels. Parasite content was labeled by outlining regions, resulting in a total of 1,620 intestinal parasites, with a particular focus on intestinal protozoa. Through image processing, non-informative and noisy regions that did not provide relevant information within the visual field were removed, yielding images with an approximately 1:1 aspect ratio and a resolution of 2,100 x 2,100 pixels.
