Each pathology image could have 10 billion pixels, and we may extract a million spatial objects per image and 100 million features (dozens to 100 features per object) per image. We often tile the image into 4K x 4K tiles for processing. We develop buffering-based tiling to handle boundary-crossing objects. For each typical study, we may have hundreds to thousands of pathology images. Bayesian . Networks. agenda. B. ayesian networks. Chain rule for . Bayes . nets. Naïve Bayes models.
