SNPGram21 - Gram stain whole slide images

Dataset introduced in the published ICPR 2022 paper "Efficient Cell Labelling for Gram Stain WSIs" The proposed SNPGram21 dataset comprises Gram stained smears which were automatically digitised into TIF format using a 63×objective lens magnification without oil immersion. This dataset contains 100 WSIs with a resolution of 20164×11828. The WSIs are obtained from six different benches comprising: Genital, Skin, Respiratory, Fluids, Ear/Eye/Nose/Throat, and Hospital. Samples from these different groups can have variant background information. Bacteria, yeast, and dipping artifacts may present in the WSIs in addition to the cells of interest which are epithelial and leukocyte cells. Each WSI was compressed to JPEG format and then the Labelme tool was used to annotate the leukocytes and epithelial cells using bounding boxes. Please refer to the paper "Efficient Cell Labelling for Gram Stain WSIs" for more details.
