摘要：
A method of determining acceptability of an image of a fingerprint to be analyzed, includes dividing the image into a plurality of blocks, determining a focus for each block, determining a validity of a block, the block being valid if the focus is sufficient, otherwise the block being invalid, totaling a number of valid blocks in the image, and determining a validity of the image, the image being valid if a number of valid blocks is sufficient.
