Abstract (en)
[origin: WO2010049415A1] Pictures can be registered using two-dimensional noise-like patterns or symbologies. Once a symbology has been discriminated in a coarse search from other elements in a captured image, it may be necessary to precisely locate some points of interest within such symbology for facilitating an accurate restoring and evaluation of that symbology. According to the invention, a predetermined original two-dimensional symbology is enriched by adding small circular noise-like patterns (MNP) at predetermined positions, which MNPs are used for improving the symbology registration by performing a related fine search.
