Abstract:
1. An imaging method for enhancing spatial resolution within an image domain of an image edge-response function of a scanned object-discontinuity, the method comprising the steps of: carrying out a de-convolution process on the image edge-response function to derive from the image edge-response function a spread profile of the respective point-spread function or line-spread function of the image edge-response function, the de-convolution process being carried out with sub-pixel sampling of the image-edge response function; correlating the spread profile with a profile of the image edge-response function; identifying within the image domain the location of the object-discontinuity, the location of the object-discontinuity being identified within the image domain by a mid-point of a full-width half-maximum of the spread profile; and redistributing sub-pixels of the profile of the edge-response function to enhance the spatial resolution of the object-discontinuity within the image domain, the sub-pixels being redistributed between two opposite sides of the identified location of the object-discontinuity in the image domain, by transferring sub-pixels on one of the two sides to the other of the two side of the identified location.
