Abstract

This paper presents an automated method for classifying scenes of laparoscope videos based on the subspace method with color information. Because laparoscopic surgery requires more collaborative work in the narrow perspective of the operator, are strongly expected to develop a navigation system that supports collaboration. This paper presents the unction for automated scene classification of laparoscopic videos as a preliminary study for achieving the intelligent assistance based on recognition of the progress of surgery and surgical evaluation. The subspace of each category is created from training dataset with color information. We applied the proposed method to a sequence of a laparoscopic video. The experimental results showed that the recognition rate of the proposed method is 79.8%.
