Abstract
Scanned image portions of virtual slide are stored in accord with a positional index metric associated to each image's location in a mosaic representation of the entire physical slide and a normalized correlation search is performed on next neighbor regional image blocks. A set of relative positional offset values and a correlation coefficient is determined for a regional image block and a next neighbor regional image block. A portion of the regional image blocks is viewed as a field of view of a display and a composite of the potion of regional image blocks is stitched together in accord with the set of relative positional offset values and the correlation coefficient, such that only the blocks comprising the portion are stitched. Moving the field of view of the display causes additional regional image blocks to be displayed, where image stitching is subsequently performed only with respect to the additional regional image blocks brought into the new field of view.
