Abstract
An apparatus includes a programmable logic configured to: convolve a stencil in a non-rotated orientation about a 2D array of pixels of a captured image received as image data from a camera to generate non-rotated stencil data; generate rotated stencil data based on a rotation of the stencil into a rotated orientation; generate, based on the non-rotated and rotated stencil data, a per-pixel density map indicative of a location of a corner of a 2D indicia within the captured image; employ noise filtering and subsampling to generate, based on the per-pixel density map, a per-tile density map indicative of the location of the corner of the 2D indicia within a 2D array of tiles that corresponds to the 2D array of pixels of the captured image; and generate, based on the per-tile density map, 2D indicia metadata indicative of the location of the 2D indicia within the captured image.
