A discrete fractional Hankel transform based on the eigen decomposition of a symmetric kernel matrix of the discrete Hankel transform

Abstract: Recently a discrete Hankel transform (DHT) has been introduced using a symmetric involutory kernel matrix T. Although Namias contributed the fractional Hankel transform (FRHT) in 1980, no ...

Learning the Kernel Matrix for Superresolution

Abstract: This paper proposes the application of learned kernels in support vector regression to superresolution in the discrete cosine transform (DCT) domain. Though previous works involve kernel ...
