LIVE Wireless
Video Quality Assessment Database
The LIVE Wireless Video Quality Assessment Database is no longer
publicly available. We have decided to take the database offline
for a number of reasons:
1. Larger, representative database with diverse content
coming soon. We are currently in the process of creating
a much larger database with better content, perceptual separation,
scales of videos, types of motion, separation and more representative
distortions. This database will greatly improve upon and modernize
our mobile/wireless VQA database efforts. Database is expected
to be completed in late Spring of 2011.
2. Limited content. The old database suffered
from very limited content, being driven by a specific application.
All of the videos were of slow-moving airplanes and related
content in a hanger. The motion content was very slow and simple.
3. Clustering of Algorithmic scores. Algorithmic
correlations with human perception on the old database have
a tendency to cluster at the 0.95-0.96 correlation level. Much
of this problem arose from the uniformity and simplicity of
content. We and others were finding it impossible to separate
the performances of objective algorithms.
Rather than continuing supplying a less diverse and effective
database with a much better one in the works, we have taken the
LIVE Wireless VQA database offline. However, there is no vacuum:
The LIVE Video Quality Assessment Database – probably the
best VQA database in existence, with excellent content, motion
diversity, and perceptual separations, and spanning a larger set
of distortions (including wireless errors) is still available
to researchers at no cost.
