Patent ID: 8675992

Claim:
A method for reconstituting an image comprising: dividing the image into a number of overlapping tiles captured in a series of snapshots and reconstituting the image with a magnification without substantial loss of accuracy; the method for reconstituting the image further comprising: capturing at least two consecutive snapshot images through a digital scanner; calculating stitch points between the at least two consecutive snapshots defining a first tile and a second tile, respectively; wherein the first and second tile images have a common overlap of at least N pixels between them; the method of calculating stitch points comprising: a. detecting and recording corner points in a minimum overlap region and a maximum overlap region, whereby detected corner points or a selected subset of corner points are sorted and maintained in a list; b. for each corner point selected in the first tile, determining a set of possible stitch points in the second tile; wherein candidate points are selected using a goodness criterion; c. maintaining a pair of stitch points that have a matching score that is greater than a defined or computed threshold; d. computing a displacement between the tiles; e. calculating a confidence score associated with the computed displacement; and f. determining a stitching point for stitching the first and second tiles; and displaying a stitched image or storing a stitched image.
