1. A method comprising: in an electronic device comprising a processor, the processor: receiving an initial image of indicia positioned behind a reflective surface; processing the initial image to produce a resulting image by: identifying an interest region of the initial image by applying an anisotropic diffusive filter to the initial image to determine the interest region, where the interest region identifies a portion of the initial image affected by glare caused by the reflective surface; texturizing the interest region to account for the glare; and removing a defocusing effect from the initial image to account for blur, reflection, or both, caused by the reflective surface; and extracting data from the resulting image representative of the indicia.
