Abstract
According to exemplary systems and methods, a template is partitioned into blocks using an image processor. An image is scanned using an optical scanner. The image is aligned to the template. Image features are matched with template features in the blocks of the template. Displacement vectors are identified for differences of the image features from the template features. Normalized cross correlation (NCC) is determined between blocks of the image and each block of the template using the image processor. Peaks in the NCC are identified. A displacement vector is selected for a peak with highest NCC for each the block of the template. Ambiguous template features are identified in the image based on the displacement vector. Blocks are iteratively combined and NCC determined to remove the ambiguous template features.
