Cognex Deep Learning can read printed barcodes on difficult backgrounds. With a pre-trained font library, the deep learning OCR tool is easy to set up and deploy. It can then be trained on a small set of images of text printed on a variety of backgrounds, and it learns to identify the text while ignoring the background. This is even the case when the text appears on new backgrounds that were not in the original training set. When text appears on a new background, the OCR tool does not need to be retrained, which keeps the production line running without interruption or loss of read accuracy.
