Blind Decomposition of Multispectral Document Images Using Orthogonal Nonnegative Matrix Factorization

By |May 9th, 2022|Categories: 2021, Publications|Tags: , |

This paper addresses the challenge of Multispectral (MS) document image segmentation, which is an essential step for subsequent document image analysis. Most previous studies have focused only on binary (text/non-text) separation. They also rely on handcrafted features and techniques dedicated […]

Forgery Detection in Hyperspectral Document Images using Graph Orthogonal Nonnegative Matrix Factorization

By |May 9th, 2022|Categories: 2020, Publications|Tags: , |

The analysis of inks plays a crucial role in the examination process of questioned documents. To address this issue, we propose a new approach for ink mismatch detection in Hyperspectral […]

Unsupervised exemplar-based learning for improved document image classification

By |May 8th, 2022|Categories: 2019, Publications|Tags: , , |

Many recent state-of-the-art approaches for document image classification are based on supervised feature learning that requires a large amount of labeled training data. In real-world problem of document image classification, the available amount of labeled data is limited and scarce […]
