Abstract:
1. A method for creating a digital representation of a signature, the method comprising: capturing an image of a signature, wherein the signature is aligned with a reference line associated with the image; identifying a central row of pixels in the captured image corresponding to the reference line; identifying a closest row of pixels above the central row of pixels that comprises a consecutive sequence of white pixels of at least a threshold length, and for which a threshold number of additional rows comprise a consecutive sequence of white pixels; identifying a top boundary within the image for the signature, wherein the top boundary comprises a row having a particular amount of light portions, wherein the top boundary comprises the identified closest row of pixels; identifying a bottom boundary within the image for the signature, wherein the bottom boundary comprises a row having a particular amount of light portions, and wherein the reference line is positioned between the top boundary and bottom boundary; and applying a vectorization process to portions of the captured image that are between the top boundary and the bottom boundary to create a representation of the image.
