Many new DCT-like transforms have been proposed since the first edition of this book. For
example, the integer DCT that yields integer transform coefficients, the directional DCT to …

This paper proposes a novel approach to jointly optimize spatial prediction and the choice of
the subsequent transform in video and image compression. Under the assumption of a …

Adaptive Signal Models: Theory, Algorithms and Audio Applications presents methods for
deriving mathematical models of natural signals. The introduction covers the fundamentals …

A novel frequency-domain technique for image blocking artifact detection and reduction is
presented. The algorithm first detects the regions of the image which present visible blocking …

Objective: The primary objective of our study is to address the challenge of confidentially
sharing medical images across different centers. This is often a critical necessity in both …

Two families of transform domain signal restoration (denoising and deblurring) and
enhancement methods well suited to processing non-stationary signals are reviewed and …

Wavelets are a new family of basis functions that can be used to approximate general
functions. They combine powerful properties such as bi orthogonality, compact support …

The modulated lapped transform (MLT) is used in both audio and video data compression
schemes. This paper describes its properties and how it can be used to generate a time …

Well-known block transforms and perfect reconstruction orthonormal filter banks are
evaluated based on their frequency behavior and energy compaction. The filter banks …
