Issue: When a barcode is wrapped on a cylindrical object such as a pop can, the resulting barcode image is curved. The deformed barcode is very challenging to scan correctly.
Solution: Dynamsoft Barcode Reader SDK provides several image processing methods to combat deformation. These helps to scan curved, crumpled, distorted and other types of challenging barcodes.
