Systems and methods for mobile image capture and processing

A system, comprising:

• a processor configured to execute logic;
• and
• logic configured to cause the processor executing the logic to:
• capture one or more of image data depicting a digital representation of a document and audio data relating to the digital representation of the document;
• define a plurality of candidate edge points within the image data,
• remove one or more outlier candidate edge points from the plurality of candidate edge points;
• define a second plurality of candidate edge points excluding the one or more outlier candidate edge points;
• and
• define four sides of a tetragon based on one or more of the plurality of candidate edge points and the second plurality of candidate edge points, wherein each side of the tetragon corresponds to a different side of the document;
• and
• output the digital representation of the document and the tetragon to a display of a mobile device, wherein the tetragon bounds the digital representation of the document.

A computer program product comprising a computer readable storage medium having computer readable program code stored thereon, the computer readable program code comprising:

• computer readable program code configured to cause a processor to:
• capture one or more of image data depicting a digital representation of a document and audio data relating to the digital representation of the document;
• define a plurality of candidate edge points within the image data,
• remove one or more outlier candidate edge points from the plurality of candidate edge points;
• define a second plurality of candidate edge points excluding the one or more outlier candidate edge points;
• and
• define four sides of a tetragon based on one or more of the plurality of candidate edge points and the second plurality of candidate edge points, wherein each side of the tetragon corresponds to a different side of the document;
• and
• output the digital representation of the document and the tetragon to a display of a mobile device, wherein the tetragon bounds the digital representation of the document.
