ABSTRACT
A hybrid version of the Haar and Walsh-Hadamard transforms (HT and WHT) called Hadamard-Haar transform (HHT),is defined and developed. Efficient algorithms for fast computation of the (HHT), and its inverse are developed. (HHT)r is applied to digital signal and image processing and its utility and effectiveness are compared with other discrete transforms on the basis of some standard performance criteria.
INDEX TERMS
Data compression, digital time processing, feature selection, Hadamard?Haar transform (HHT)r, Wiener filtering.
