Abstract
In this paper, an MPEG-7 based album
system for managing consumer-generated
photographs is introduced. Face detection and
recognition technologies are adopted to
implement the query-by-face functionality of the
content-aware album. A convenient face
database construction and training mechanism is
also provided. By utilizing both user attention
model for visual objects and face information,
the most representative region within a
photograph, the so-called photo focus, can be
easily extracted. Furthermore, with the aid of
photo focus and objects importance calculated
based on user attention models, two intelligent
thumbnail creation approaches, superior to the
commonly used sub-sampling method, are also
proposed. At last, the face information is
incorporated with MPEG-7 visual descriptors to
facilitate the similarity calculation between
images, allowing users to perform similarity
search operations in our album system. The
major functionalities introduced have
contributed to form a content-aware album
system for consumer-generated photographs.
