Title: STUDY OF ORTHOGONAL TRANSFORMS FOR PICTURE SIGNALS
Authors: Sharma, Narendra Kumar

Abstract: Hotelling was the first to derive and publish the transformation that transforms discrete variables into uncorre-lated coefficients. He referred to this technique as "The method of principal ccmponents". During the past twenty years the application of electronic imagery have grown enormously. This growth has placed severe demands on the capabilities of communication systems, since conventional television transmission requires exceptionally wide bandwidths. One means of band, idth reduction is transform image coding process L 51. In transform coding, an alternative representation of the signal is made first by .taking linear combinations of samples in a block of data (called the coefficients) and the quantizing the selected coefficients for transmission.
