Title: DETECTING ORIENTATION OF TEXTUAL DOCUMENTS ON A LIVE CAMERA FEED
Abstract:
The present disclosure relates to the extraction of text from an image including a depiction of a document. According to one embodiment, a mobile device receives an image depicting a document. The mobile device identifies a plurality of text areas in the document and identifies a midpoint of each of the plurality of text areas in the document. The mobile device detects one or more lines of text in the document including a plurality of text areas, where the plurality of text areas included in a line of text are associated with a midpoint having a coordinate within a threshold number of pixels on one axis in a two-dimensional space. Based on an orientation of the detected one or more lines of text, the mobile device determines a probable orientation of the document and extracts text from the image based on the determined probable orientation of the document.
