Identification of candidate regions in images for predefined object placement

A method comprising:

• receiving, by a processor, an image of a document;
• identifying, by the processor, contents in the received image;
• identifying, by the processor, candidate regions on the received image at which a signature object is insertable;
• assigning, by the processor for each of the identified contents, respective scores to the identified candidate regions based on relative positions of the identified candidate regions with respect to a respective one of the identified contents in the image;
• based on the assigned scores, selecting, by the processor, a candidate region among the identified candidate regions at which the signature object is to be inserted;
• determining, by the processor, a size and a position of the signature object based on the selected candidate region;
• and
• outputting, by the processor, the determined size and the position of the signature object to be inserted on the received image.

A non-transitory computer-readable medium on which is stored machine-readable instructions that when executed by a processor, cause the processor to:

• receive an image of a document;
• identify candidate lines on the received image at which a signature object is insertable in the received image;
• assign scores to the identified candidate lines based on relative positions of respective ones of the identified candidate lines to respective contents in the received image;
• based on the assigned scores, select a signature line among the identified candidate lines at which the signature object is insertable;
• determine a size and a position of the signature object based on the selected signature line;
• and
• output the determined size and the position of the signature object on the received image.
