Abstract: We
propose a new type of saliency – context-aware saliency – which aims at
detecting the image regions that represent the scene. This definition
differs from previous definitions whose goal is to either identify
fixation points or detect the dominant object. In accordance with our
saliency definition, we present a detection algorithm which is based on
four principles observed in the psychological literature.To
evaluate the proposed algorithm for saliency detection we further
propose an approach for automating collage construction, which is based
on assembling regions of interest of arbitrary shape in a puzzle-like
manner. We show that this approach produces collages that are
informative, compact, and eye-pleasing. This is obtained by following
artistic principles and assembling the extracted cutouts such that
their shapes complete each other.
