Abstract (in Japanese) (See Japanese page) 
(in English) This paper reports a bleeding region segmentation method in laparoscopic videos based on U-Net for laparoscopic surgery assistance.
Researches on recognition of surgical process have been conducted by analyzing laparoscopic videos for assisting laparoscopic surgery.
We have focused on bleeding areas during surgery and have segmented bleeding areas from laparoscopic videos using U-Net.
Since our previous method processed frame by frame in the videos, time-series smoothness was lost in the results.
In this paper, we construct U-Net which considers time series information.
In the experiment, we segmented the bleeding area in laparoscopic surgery videos by the previous method and proposed method.
The experimental results showed that the bleeding region was extracted with continuity between frames by using multiple consecutive frames as input.
