A new two-dimensional (2D) Walsh transform scheme is presented based on a block splitting technique.
We used a simple denoising strategy to evaluate the performance of the proposed transform scheme.
Next, the frequency domain estimation methods, based on the sub-system concept are reviewed, and an inverse Fourier transform scheme is introduced.
A complete orthogonal basis set corresponds to a kind of multiwavelet packet transform scheme, a subset of the library and a parameter set {k, l}.
This is because with an appropriate higher balanced order, the transform scheme provides more effective sparse image representation, a higher band number provides more flexible spatial-frequency domain partitioning, and the most suitable basis set for an analyzed signal can be selected for the multiwavelet packet transform scheme.
The remote sensing image denoising method based on this transform scheme is then described, and its utility is demonstrated by illustrative results of its application to denoise remote sensing images.
