The image can be decomposed into subimages such that pixels in each subimage have the same singularity coefficients. Since each subimage is fractal, the overall image can have singularity spectrum. For a wavelet-based measure, it is possible to reconstruct the image from the singularity information...

Biorthogonal wavelet filters have linear phase which is very critical for image processing. Using a biorthogonal wavelet will not introduce visual distortions in the image. An orthogonal transform does not color white noise. If white noise is provided as input to an orthogonal transform, the output...
