Certified Neural Network Watermarks with Randomized Smoothing

1 code implementation16 Jul 2022 Arpit Bansal, Ping-Yeh Chiang, Michael Curry, Rajiv Jain, Curtis Wigington, Varun Manjunatha, John P Dickerson, Tom Goldstein

Watermarking is a commonly used strategy to protect creators' rights to digital images, videos and audio.

Was my Model Stolen? Feature Sharing for Robust and Transferable Watermarks

no code implementations29 Sep 2021 Ruixiang Tang, Hongye Jin, Curtis Wigington, Mengnan Du, Rajiv Jain, Xia Hu

The main idea is to insert a watermark which is only known to defender into the protected model and the watermark will then be transferred into all stolen models.

RPCL: A Framework for Improving Cross-Domain Detection with Auxiliary Tasks

no code implementations18 Apr 2021 Kai Li, Curtis Wigington, Chris Tensmeyer, Vlad I. Morariu, Handong Zhao, Varun Manjunatha, Nikolaos Barmpalios, Yun Fu

Contrasted with prior work, this paper provides a complementary solution to align domains by learning the same auxiliary tasks in both domains simultaneously.

Start, Follow, Read: End-to-End Full-Page Handwriting Recognition

1 code implementation ECCV 2018 Curtis Wigington, Chris Tensmeyer, Brian Davis, William Barrett, Brian Price, Scott Cohen

Despite decades of research, offline handwriting recognition (HWR) of degraded historical documents remains a challenging problem, which if solved could greatly improve the searchability of online cultural heritage archives.

Language Model Supervision for Handwriting Recognition Model Adaptation

no code implementations4 Aug 2018 Chris Tensmeyer, Curtis Wigington, Brian Davis, Seth Stewart, Tony Martinez, William Barrett

Training state-of-the-art offline handwriting recognition (HWR) models requires large labeled datasets, but unfortunately such datasets are not available in all languages and domains due to the high cost of manual labeling. We address this problem by showing how high resource languages can be leveraged to help train models for low resource languages. We propose a transfer learning methodology where we adapt HWR models trained on a source language to a target language that uses the same writing script. This methodology only requires labeled data in the source language, unlabeled data in the target language, and a language model of the target language.

PageNet: Page Boundary Extraction in Historical Handwritten Documents

3 code implementations5 Sep 2017 Chris Tensmeyer, Brian Davis, Curtis Wigington, Iain Lee, Bill Barrett

When digitizing a document into an image, it is common to include a surrounding border region to visually indicate that the entire document is present in the image.
