Normalized confusion matrix showing the accuracy achieved separately for each surgical phase. The critical phases in an LC procedure are in bold; 92% of the Calot triangle dissection phase frames were correctly classified and 96% of the gallbladder dissection frames were correctly classified. (Please note that the rows of the confusion matrix do not precisely sum to 1 due to rounding.)
