![]() What we have then, is 65 particles that we can classify. or some sort of simple gauging.īut right now I’m assuming you can get a clear, clean image, thresholded, and at an upright angle (if you need help with that, you are gonna have to provide source images). ![]() Intuitively I’d do some edge detection horizontally across barcode (1 edge polarity), get the edge coordinates of the trackers and then either use edge detection again on top and bottom of this. This reading is easy, and there is a number of ways to get to Rome. That means, the code above encodes those 65 characters:įTAAFDTDFTAFDFFFTADAFTTDFTFDFAFDTDTTDFFADFTADTADAFADFTFFFAAATDTDF I lifted the following graphic from Wikipedia (its public domain), it explains what it is. This barcode describes 4 kinds of characters : A = Ascending bar, D = Descending bar, F = Full bar, T or S = Track (short) bar ![]() but will warn you that how I wrap that decoder is a bit ugly. The first step is done with image processing, the second with a JavaScript decoder provided by. IMB barcode reading is a 2-step process: First, the image with the bars is read, and converted into a 65-character string representing the tracking code, and then a decoder is used to convert that into 20-digit tracking (Barcode ID, Service IT, Mailer ID, Sequence Number) and up to 11 ID Routing Info. ![]()
