This book contains high-quality research articles and reviews that
promote research and reflect the most recent advances in intelligent
wavelet based techniques for advanced multimedia applications as well as
other emerging areas. In recent time, wavelet transforms have become
useful in many signal, image and video processing applications,
especially for multimedia security and surveillance. A few applications
of wavelets in security and surveillance are watermarking, fusion,
steganography, object detection, tracking, motion recognition and
intention recognition, etc. Wavelets are well capable of analyzing
signal, image and video at different resolution levels, popularly known
as multiresolution analysis. The multiresolution analysis is
advantageous in multimedia security and surveillance applications. It
provides flexibility in selection of different resolution levels that
leads to better accuracy. Furthermore, recently sparse representation
has become an advancement to analyze wavelet coefficients. It is
observed that wavelet transforms possess the invariance property which
makes them suitable for many vision applications.
This book provides a concise overview of the current state of the art
and disseminates some of the novel and exciting ideas and techniques. In
addition, it is also helpful for the senior undergraduate and graduate
students, researcher, academicians, IT professional and providers,
citizens, customers as well as policy makers working in this area as
well as other emerging applications demanding state-of-the-art wavelet
based multimedia applications.
