1. A method for determining by a computing device an inconsistency in an image, wherein the image is translated from a vector pattern and the method comprises steps of: aligning the image to the vector pattern including an original design of the image; quantizing the vector pattern into a plurality of first points; calculating geometric features of the plurality of first points; identifying from the image a plurality of second points corresponding to the plurality of first points; comparing measurement values of second points with identical geometric features; and determining the inconsistency in the image based on said step of comparing.
