Orthogonal multifilters image processing of astronomical images from scanned photographic plates
It offers a new tool for astronomical image processing, but the contribution is incremental as it applies existing multiwavelet concepts to a specific domain.
The paper presents orthogonal multifilters derived from Haar and Daubechies wavelets for processing astronomical images from scanned photographic plates, demonstrating their application in multifilter decomposition.
In this paper orthogonal multifilters for astronomical image processing are presented. We obtained new orthogonal multifilters based on the orthogonal wavelet of Haar and Daubechies. Recently, multiwavelets have been introduced as a more powerful multiscale analysis tool. It adds several degrees of freedom in multifilter design and makes it possible to have several useful properties such as symmetry, orthogonality, short support, and a higher number of vanishing moments simultaneously. Multifilter decomposition of scanned photographic plates with astronomical images is made.
