A computer-implemented and a device for analysis of a digital cytology slide of a biological sample. The biological sample having been previously collected from a subject suspected to be suffering from bladder cancer, the device including: at least one input configured to receive at least one digital cytology slide obtained from the biological sample; at least one processor configured to: detect cells of interest from the at least one digital cytology image; for each cell of interest, compute a features vector including at least one feature calculated on each cell of interest; define a bag of k instances for each digital cytology slide; calculating a global prediction score representative of a probability of presence of bladder cancer and/or a stage of bladder cancer for the subject; at least one output configured to provide the global prediction score.

Method for identifying abnormalities in cells of interest in a biological sample

A method for classifying and counting objects recoverable from a urine sample processed onto a slide. The method includes the following steps: receiving at least one digitalized image of the whole slide; detecting connected components by segmentation of the image of the whole slide; classifying the detected connected components into countable connected components and uncountable connected components using a classifier; for the countable connected components using an object detection model to obtaining the number of objects for each class; for the uncountable components using a semantic segmentation model to obtaining the number of objects for each class; summing up the number of objects for each class obtained from the semantic segmentation model and the object detection model outputting a number of objects for each class.
