Abstract
A DIGITAL ENCODING SCHEME FOR THE ARCHIVAL, STORAGE, AND SUBSEQUENT TRANSMISSION OF COLOR GRAPHIC IMAGES WILL BE DEVELOPED. THIS SCHEME WILL ACCOMMODATE RAPID RESPONSE TIMES AND ALLOW FOR FUTURE IMPROVEMENTS AND MODIFICATIONS IN A WELL-DEFINED AND ECONOMIC MANNER. THE TECHNIQUE PROPOSED TO ACCOMPLISH THIS TASK IS BASED ON A PICTURE MATRIX TRANSFORMATION, WHICH IS BASED ON THE S-TRANSFORM CODING SCHEME (A DERIVATION OF THE HADAMARD TRANSFORM). THIS TRANSFORM WILL CONVERT AN INPUT PICTURE (2 DIMENSIONAL PIXEL MATRIX) TO A PRI MARY MATRIX AND VARIABLE NUMBER OF SECONDARY MATRICES. THE PRIMARY MATRIX IS DERIVED BY SUCCESSIVE TRANSFORMATIONS OF THE INPUT PICTURE, EACH OF WHICH REDUCES THE PICTURE RESOLUTION BY ONE HALF. THE INPUT MATRIX IS PARTITIONED INTO SUB-MATRICES WITH DIMENSIONS OF TWO PIXELS SQUARE. NEXT A SUMMING IS PERFORMED--THEN REPEATED UNTIL THE DESIRED RESOLUTION IS ACHIEVED. DEPENDING ON THE APPLICATION, THE DEFINITION OF THE PRIMARY MATRIX CAN BE ALTERED TO GIVE A DIFFERENT ASPECT RATIO,THUS MAKING THE CODE VIRTUALLY DEVICE INDEPENDENT.
