Application Of Hadamard, Haar, And Hadamard-Haar Transformation To Image Coding And Bandwidth Compression
Ryszard S. Choraś · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1983
The paper presents a numerical techniques of transform image coding for the image codklg for the image bandwidth compression. Unitary transformations called Hadamard, Haar and Hadamard-Haar transformations are definied and developed. 'Te described the construction of the transformation matrices and presents algorithms for computation of the transformations and theirs inverse. Considered transformations are asolied to iiaa e processing and theirs utility and effectiveness are compared with other discrete transforms on the basic of some standard performance criteria.
