Query: Wavelet-based Scale Saliency   Both pixel-based scale saliency (PSS) and basis project methods focus on
multiscale analysis of data content and structure. Their theoretical relations
and practical combination are previously discussed. However, no models have
ever been proposed for calculating scale saliency on basis-projected
descriptors since then. This paper extend those ideas into mathematical models
and implement them in the wavelet-based scale saliency (WSS). While PSS uses
pixel-value descriptors, WSS treats wavelet sub-bands as basis descriptors. The
paper discusses different wavelet descriptors: discrete wavelet transform
(DWT), wavelet packet transform (DWPT), quaternion wavelet transform (QWT) and
best basis quaternion wavelet packet transform (QWPTBB). WSS saliency maps of
different descriptors are generated and compared against other saliency methods
by both quantitative and quanlitative methods. Quantitative results, ROC
curves, AUC values and NSS values are collected from simulations on Bruce and
Kootstra image databases with human eye-tracking data as ground-truth.
Furthermore, qualitative visual results of saliency maps are analyzed and
compared against each other as well as eye-tracking data inclusive in the
databases.
