Claim One:
1. A computer-implemented method for verifying a direct part mark inspection code, the method comprising: acquiring an image of the code; attempting, using one or more processing devices, to decode the code using the image; and if the attempt to decode the code is unsuccessful: locating the code, using the one or more processing devices, in the image to provide a code location; and measuring, using the one or more processing devices, aspects of a mark quality using the image and the code location in the image; wherein the step of measuring the aspects of the mark quality includes one of more of: calculating a quality of a continuous finder pattern based on one or more of a ratio of actual to expected dark modules in the continuous finder pattern, a ratio of actual to expected light modules in the continuous finder pattern, and a ratio of dark to light pixels in solid lines of the continuous finder pattern; calculating a quality of a discontinuous finder pattern based on one or more of a ratio of actual to expected dark modules in the discontinuous finder pattern, and a ratio of actual to expected light modules in the discontinuous finder pattern; and performing a histogram analysis on a quiet zone in the image.
