abstract = {Organizing images into semantic categories can be very
useful for searching and browsing through large image repositories. In
this work, we use machine learning to associate low level colour
representations of digital colour photos with their high level semantic
categories. We investigate the redundancy and performance of a number
of histogram-based colour image content representations in the context
of automatic colour photo categorization using support vector machines.
We use principal component analysis to reduce the dimensionality of
(high dimensional) histogram based colour descriptors and use support
vector machines to learn to classify the images into various high level
categories in the histograms subspaces. We present experimental results
to demonstrate the usefulness of such an approach to organizing colour
photos into semantic categories. Our results show that the colour
content descriptors constructed in different ways perform quite
differently and the performances are data dependent hence it is
difficult to pick a "winning" descriptor. Our results demonstrate
conclusively that all descriptors studied in this paper are highly
redundant and that regardless of their performances, the
dimensionalities of these histogram based colour content descriptors
can be significantly reduced without affecting their classification
performances.},
