Outline of the clinical workflow analysis pipeline. Stepwise approach to second-trimester workflow analysis: (1) partitioning—automatically extraction of 5-s clips from the videos that represent important events; (2) manual labeling of the training dataset; (3) training a spatiotemporal deep network; (4) automatic labelling of the entire dataset; and (5) analysis of second-trimester scans as a sequence of organs being scanned.
