Abstract : In image-guided surgery, a new generation of Computer-Assisted- Surgical CAS systems based on information from the Operating Room OR has recently been developed to improve situation awareness in the OR. Our main project is to develop an application-dependant framework able to extract high- level tasks surgical phases using microscope videos data only. In this paper, we present two methods: one method to segment the pupil and one to extract and recognize surgical tools. We show how both methods improve the accuracy of the framework for analysis of cataract surgery videos, to detect eight surgical phases.
