Title
Leveraging Lanczos Algorithm for Computation of Eigenbasis in Type I Discrete Sine Transform
Type Presentation
Keywords
eigenvalue, eigenvector, discrete trigonometric transform, Lanczos algorithm
Abstract
The main contribution lies in presenting an application of the Lanczos algorithm to provide an eigenbasis for a specific type of discrete Sine transform, referred to the signal processing literature as DST of type one. This method, suggesting a new approach, opens up new possiblilities for finding the eigenbasis of other discrete trigonometric transforms, which serve as the key tool in image and video compression.
