ParasitoBank: Dataset of helminths and protozoa in coprology samples

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. The labeling information was organized in a JSON file following the “Common Objects in Context” (COCO) format, which was combined with the folder containing the images into a compressed file.

本数据集包含经显微镜分析的新鲜粪便样本视觉场图像共779张。这些图像由摩托罗拉G84手机以3,072 x 3,072像素和3,072 x 4,080像素的分辨率获取。寄生虫含量通过描绘区域进行标注，总计标注了1,620个肠道寄生虫，尤其关注肠道原生动物。通过图像处理，移除了视觉场中非信息性和噪声区域，从而得到约1:1长宽比、2,100 x 2,100像素分辨率的图像。标注信息按照“上下文中的常见对象”格式（COCO格式）组织在一个JSON文件中，并与包含图像的文件夹一起压缩。
