摘要
An optimum hexagonal sampling structure for use with a raster scan input device is described. A set of local operators for detecting object edges within the image is designed and the accuracy shown to be high when compared with similar operators for use in the conventional square structure. It is also noted that hexagonal Fourier plane operators exist. A comparison between equivalent processing times for systems implemented on a popular processor is presented and a saving in excess of 40% is demonstrated.
