Digital Image Processing - Chapter 2: Image Transform - Nguyen Viet Dung
(Bản scan)
Energy Compaction and Variances of Transform Coefficients. Most unitary transforms have a tendency to pack a large fraction of the average energy of the image into a relatively few components of the transform coefficients.
Decorrelation
• When the input vector elements are highly correlated, the transform coefficients
tend to be uncorrelated.
