BEIJING, July 1, 2019 /PRNewswire/ -- iQIYI, Inc. (NASDAQ:
IQ) ("iQIYI" or the "Company"), an innovative market-leading online
entertainment service in China,
and ACM International Conference on Multimedia ("ACM MM")'s jointly
held 2019 Celebrity Video Identification Challenge (the
"Challenge") officially came to a close after three months of
competition. At this year's AI competition, a total of 255 teams
including iQIYI along with top foreign and domestic universities,
such as Carnegie Mellon University,
University College London, University of Exeter, Tsinghua
University, Peking University, as well as well-known companies,
such as Baidu, ZTE, JD.com, Meitu, and Nvidia, worked together to
once again make a major breakthrough in video-based multimodal
person identification technology. An accuracy rate of 91.14% was
achieved by the team from Beijing
University of Posts and Telecommunications' ("BUPT") Automation
School, who won first place.
Liu Wenfeng, iQIYI's Chief Technology Officer and President of
Infrastructure and Intelligent Content Distribution Business Group
(IIG), said, "The Challenge
continues to make breakthroughs. In addition to adding important
value to iQIYI's entertainment environment, it also creates
far-reaching effects on the advancement of person identification
technology as well as academic research and
professional training in the field."
In recent years, many tech companies and academic institutions
around the world have released video datasets to improve the
accuracy of person recognition to better solve many of the
difficult problems in the video industry. Among them, Oxford University has released the VoxCeleb2
dataset, which includes more than 6,000 human figures
and 150,000 videos, to focus on solving the problem of speaker
recognition. In order to better decipher characters in videos, the
Chinese University of Hong Kong and
SenseTime jointly released CSM data sets, which includes 1,218
characters and 127,000 videos. The YouTube Faces DB developed at
Tel Aviv University in Israel has 3,425 video clips and 1,595
characters to solve face recognition problems in constrained
environments.
At the contest, iQIYI announced a more challenging, detailed
data set, iQIYI-VID-2019, with 10,000 celebrity figures, 200 hours
of content, and 200,000 video clips of films, dramas and short
videos, which was more relevant to the actual application
scenarios. The data set included four kinds of multimodal features:
face, head, body, and voiceprint. The participating teams did not
need to use their own computing resources to extract these
features, which greatly reduces the threshold for hardware
resources in the competition, attracts more top academic teams from
around the world, and accelerates the continuous evolution of
facial recognition technology. The BUPT Automation School team, who
won first place, re-extracted the facial feature on
aligned faces and used these five types of modal features to
train a multimodal classification model, improving the accuracy
rate of the multimodal identification technology to 91.14%,
increasing 2.5pp from last year.
The latest multimodal algorithms used at the competition will be
valuable to iQIYI's many services, such as improving the HomeAI
voice interactive platform, enhancing the user's video interaction
experience, making AIWorks intelligent video content more accurate
in long-form videos, generating short-form video content more
quickly, and further elevating the efficiency of iQIYI "iMAM"
(iQIYI Media Asset Management) to create high-quality content. In
the future iQIYI will continue to cooperate with both domestic and
foreign academic institutions and industry leaders to continuously
improve the exploration and implementation of cutting-edge
technology.
