Title: Making Sense of Big Visual Data

Date: Tuesday, March 1st, 2016

Time: 10:30-12pm

Place: EV3.309

ABSTRACT

Motivated by the previous success in mining structured data
(e.g., transaction data) and semi-structured data (e.g., text), it has
aroused our curiosity in finding meaningful patterns in non-structured
visual data like images and videos. Although the discovery of visual
patterns appears to be quite exciting, data mining techniques that are
successful in business and text data may not be simply applied to
image and video data that are usually described by high-dimensional
features and exhibit spatial or spatio-temporal structures. Unlike
transaction and text data that are composed of discrete elements
without much ambiguity (i.e. predefined items and vocabularies),
visual patterns generally exhibit large variations in their visual
appearances and structures, thus challenge existing data mining
techniques. This talk will discuss our recent work of discovering and
searching visual patterns in image and video data. The topics cover
visual pattern discovery and search, video anomaly detection, as well
as their applications in image search, video surveillance, and
robotics.
