A Survey on Surgical Phase Recognition Approaches

Laparoscopic surgeries are famous due to its numerous advantages. Video based monitoring is incorporated among such surgeries. These are really useful for the surgeons for performing the surgery. Surgical tool detection and phase or workflow recognition are the major issues in medical field. These are really useful for training surgeons and clinicians. It has also applications in robot-assisted surgery. Since a video camera is inserted along with the tools, no additional setups are needed. These are the reasons behind the popularity of tool detection and workflow recognition tasks. This paper presents some of the common phase recognition approaches. The advantages and disadvantages of these methods are also discussed.
