Abstract :
This paper discusses, the classification of Hadamard transform coefficients. It is shown that the coefficient vectors can be classified into a small number of residue classes for a modulus equal to an integer power of 2. It is suggested that the result can be used to define an efficient product code for lossless coding of digital images
