End-to-End Unsupervised Document Image Blind Denoising
Mehrdad J Gangeh, Marcin Plata, Hamid Motahari +1
Removing noise from scanned pages is a vital step before their submission to the optical character recognition (OCR) system. Most available image denoising methods are supervised w…
Semi-supervised Dictionary Learning Based on Hilbert-Schmidt Independence Criterion
Mehrdad J. Gangeh, Safaa M. A. Bedawi, Ali Ghodsi +1
In this paper, a novel semi-supervised dictionary learning and sparse representation (SS-DLSR) is proposed. The proposed method benefits from the supervisory information by learnin…
On the Invariance of Dictionary Learning and Sparse Representation to Projecting Data to a Discriminative Space
Mehrdad J. Gangeh, Ali Ghodsi
In this paper, it is proved that dictionary learning and sparse representation is invariant to a linear transformation. It subsumes the special case of transforming/projecting the…
Supervised Dictionary Learning and Sparse Representation-A Review
Mehrdad J. Gangeh, Ahmed K. Farahat, Ali Ghodsi +1
Dictionary learning and sparse representation (DLSR) is a recent and successful mathematical model for data representation that achieves state-of-the-art performance in various fie…
