1. A system, comprising:
a non-transitory memory; and
one or more hardware processors coupled with the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:
receiving an image comprising a digital representation of a document;
generating a first transformed image based on performing a first transformation to the image using a horizontal line kernel;
identifying a plurality of horizontal edges on the image based on the first transformed image;
generating a second transformed image based on performing a second transformation to the image using a vertical line kernel;
identifying a plurality of vertical edges on the image based on the second transformed image;
constructing a quadrilateral using two vertical edges from the plurality of vertical edges and two horizontal edges from the plurality of horizonal edges; and
extracting a portion of the image within the quadrilateral as the digital representation of the document.
