摘要： A method and system for enhancing measurement of a bar code or other object includes storing a pixel image containing a bar code; determining bar code orientation relative to the stored pixel image; determining a scan track through the pixel image in a succession of pixel to pixel scan paths; determining the angle of each scan path relative to the bar code orientation; and adjusting the number of virtual pixels added to each scan path as a function of the scan path angle and the bar code orientation for equalizing the lengths, measured in pixels, of the scan paths though they are of different actual lengths due to differences in scan path angles.

摘要： A method and system for verifying readings of contrasting elements such as bar code elements includes generating a profile of the contrasting elements; identifying a first zone (130) of values representing a first contrasting element, a second zone (132) of values representing a second contrasting element, and a working zone (128) of values representing transitions between contrasting elements; detecting a change in the bar code profile indicative of an apparent transition between the contrasting elements and confirming the apparent transition as a true transition if it occurs in the working zone and rejecting it if it occurs in the first or second zones.
