We created this dataset from the experiments conducted in water lab of TU Delft (Stevinweg 1, Delft, Netherlands). The experiment details can be found in the publication. This dataset includes microscope images and mask annotations, that shows the shape and location of free particles and entrapped particles in images. The images are stored in the images.zip file, the annotations are stored in the labels_txt.zip file, and the classes of the annotation (i.e., entrap particle and free particle) is stored in the classes.txt file. The filenames of images and annotations includes three parts: Sampling time (the first part), the diameter of biomass (the middle part), and image number (the last part). Details of the first two parts and their meanings are provided in the following table.
