Figure detection and part label extraction from patent drawing images
Jaco Cronje · 2012
The US Patent and Trademark Office, together with the NASA Tournament Lab, launched a contest to develop spe-cialized algorithms to help bring the seven million patents presently in the patent archive into the digital age. The contest was hosted by TopCoder.com, the largest competitive online software developer community. The challenge was to detect, segment and recognize figures, captions and part labels from patent drawing images. The solution presented in this work was the winning submission.
