 The videos of surgical operations such as endoscopic videos, microscopic videos, and OR videos, are a rich source of data, that can reveal surgical improvement points and thus greatly benefit the improvement of surgical procedures.

For this purpose, a software system, Video Annotation Software, is designed and developed to enhance data extraction from the videos of different types of surgery. In addition to the surgical video analysis, the software system has the potential for many other video analyses in other fields.
