Abstract:
1. A method for communicating area information in a common framework implemented on hardware, comprising the steps of: providing to the hardware a first set of instructions which generates an area of interest (AOI) defined by a first geometric shape; defining with the hardware the first geometric shape by one or more coordinates; and converting with the hardware the one or more coordinates to a second set of coordinates for use with a second set of instructions different than the first set of instructions, wherein the second set of coordinates is defined by a new AOI which includes information associated with the first set of instructions and which is interpreted by the second set of instructions, wherein the new AOI associated with second set of instructions define a second geometric shape, wherein the step of defining the first geometric shape includes the steps of determining whether the first geometric shape includes one of: (i) at least three points; (ii) a distinct starting point, fast end point and a slow end point; (iii) a non-zero distance between a starting point and a fast end point; and (iv) a non zero area, and wherein after the determination of the first geometric shape, the method includes the steps of providing: (i) the at least three points used to define a polygon; (ii) the distinct starting point, fast end point and a slow end point used to define a parallelogram; (iii) the non-zero distance between the starting point and the fast end point used to define a rectangle; and (iv) the non zero area used to define a bounding box.
