Abstract
Visual system of human beings does not process the complete area of image
rather focus upon limited area of visual image. But in which area does the visual attention
focused is a topic of hot research nowadays. Research on psychological phenomenon
indicates that attention is attracted to features that differ from its surroundings or the one
that are unusual or unfamiliar to the human visual system. Detection of visually salient
image regions is useful for applications like object segmentation, adaptive compression, and
object recognition. Object or region based image processing can be performed more
efficiently with information pertaining locations that are visually salient to human
perception with the aid of a saliency map. Recently many authors have used wavelet domain
for detection of salient regions. This domain has shown promising results but almost all the
authors have ignored the detail components of wavelet domain which may have some useful
information. So in this paper we have tried to use the wavelet domain method to detect
salient regions using approximation and all detail components. Further this saliency map
will be used for steganography.
