Image processing with nonseparable multiwavelets
In a general context we introduce image processing with 1-dimensional wavelets and show the diferences with nonseparable 2-dimensional wavelets having quincunx decimation, in the first place, and with balanced nonseparable 2-dimensional multiwavelets, in the second place. All of them are orthogonal....
