HP Competition on Automated Mosaicing of Torn Paper Documents

HP Logo ICVGIP 2008

Congratulations Encouragement Award Winners!!

Mr. Santosh Kumar Adarkatti and Mr. Shreyamsha Kumar B. K
Research Staff
Central Research Laboratory

(R&D Unit of Bharat Electronics)

The winners get an award of Rs. 10,000/- and free registration and AC-III train fare to ICVGIP venue at Bhubaneswar.


The goal is to seamlessly stitch randomly torn paper documents in an automated fashion. The state of the art can
handle up to 50 torn pieces. The challenge is to come up with an innovative algorithm that could potentially handle more pieces, or implement existing algorithms in a faster way. The training dataset would be provided, and the test dataset would be used to compare entries. The training dataset would contain the original document as well as the torn pieces.

The method has innumerable applications in the fields of information forensics, heritage preservation etc.

If you intend to enter then please register. Registration information, details of data etc are provided below.
