Abstract:
A method for converting a Cartesian system of discrete data elements to a polar system of discrete data elements, each Cartesian element having a corresponding data value, comprising:dividing each Cartesian element into subelements;designating one of the subelements as a polar system origin;defining a polar system about said origin comprising an intersecting plurality of radial sector lines and a plurality of confocal arcs formed of said subelements, said sector lines and arcs defining boundaries of polar elements;for each subelement within the boundaries of a polar element, determining a subelement data value derived from the data value of the Cartesian element from which the subelement was divided; andcalculating a data value for each polar element based on the data values of the subelements within the boundaries of the polar element.
