  The stereo correspondence and reconstruction of endoscopic data sub-challenge
was organized during the Endovis challenge at MICCAI 2019 in Shenzhen, China.
The task was to perform dense depth estimation using 7 training datasets and 2
test sets of structured light data captured using porcine cadavers. These were
provided by a team at Intuitive Surgical. 10 teams participated in the
challenge day. This paper contains 3 additional methods which were submitted
after the challenge finished as well as a supplemental section from these teams
on issues they found with the dataset.
