AlpVision has given its iPhone authentication app a welcomed update, namely better detection of labels for curved surfaces. As opposed to flat surfaces, round labels have different depths of field and focus, and generate geometrical distortions. By enhancing the algorithms used to detect AlpVision Cryptoglyph® on flat surfaces, the updated app can now recognize a Cryptoglyph laid out over a curved surface, while counteracting the label distortions. AlpVision’s adapted app applies to a wide variety of products, including vial labels, wine & spirits rectangular or neck labels, and aerosol spray can labels, to name a few. The same application can also authenticate AlpVision Fingerprint, applicable to curved plastic molded parts. Working in real-time, verification takes less than 3 seconds, including time to pick up the item and position the iPhone over it.
