摘要
This archive contains the models and the results of the deep learning experiments published in Kloster et al. 2022: Improving deep learning-based segmentation of diatoms in gigapixel-sized virtual slides by object-based tile positioning and object integrity constraint. The folders contain models and results of each of the 24 training runs, the files “metrics.experiments.pt[prediction score threshold].csv contain segmentation score thresholds the models obtained on unknown evaluation data. The data pertaining to each model is stored in a separate folder. Its name follows the convention “experiment.[model architecture].[tiling method].[dataset size].[timestamp]”. Please note that the naming of the tiling method differs from the manuscript; “fixed” refers to fixed-stride tiling, “objectcentred” object-based positioning, and “objectcentred_with_cropped” to object-based positioning + object integrity constraint. Dataset size “10p” refers to a 10% subsample of the complete training data set, “25p” to a 25% subsample and so on. Each folder contains the best performing model of the corresponding training run as pth (Mask R-CNN, PyTorch) or h5 (U-Net, Tensorflow/Keras) file, along with a files describing setup and conduction of the training. Subfolders “test_images_segmented*” contain the segmentation predicted by the models on the evaluation data. These are supplied as 1.) mask image either with the intensity value representing the prediction score (score 0.0 – 1.0 = intensities 0 – 255) or thresholded by the prediction score threshold given in the folder name; 2.) input image overlayed with ground truth (red) and segmentation mask (green), resulting in TP marked in yellow; 3.) a CSV file giving info on the filenames and the segmentation performance metrics. Please refer to the manuscript for further details.
