Modern Trends in Hyperspectral Image Analysis: A Review
TL;DR: This review focuses on the fundamentals of hyperspectral image analysis and its modern applications such as food quality and safety assessment, medical diagnosis and image guided surgery, forensic document examination, defense and homeland security, remote sensing applicationssuch as precision agriculture and water resource management and material identification and mapping of artworks.
Journal ArticleDOI
Deep learning for automated forgery detection in hyperspectral document images
TL;DR: The proposed method effectively identifies different ink types in a hyperspectral document image for forgery detection and achieves an overall accuracy of 98.2% for blue and 88% for black inks, which is the highest accuracy among the latest techniques of ink mismatch detection on theWIHSI database.
Proceedings ArticleDOI
Automated Forgery Detection in Multispectral Document Images Using Fuzzy Clustering
TL;DR: An efficient automatic ink mismatch detection technique is proposed which uses Fuzzy C-Means Clustering to divide the spectral responses of ink pixels in handwritten notes into different clusters which relate to the unique inks used in the document.
Proceedings ArticleDOI
Towards Automated Ink Mismatch Detection in Hyperspectral Document Images
TL;DR: The presented approach deals with ink mismatch detection in unbalanced clusters by using hyperspectral unmixing scheme and shows that HySime outperforms other methods in signal subspace estimation and will further encourage the use of hyperspectrals imaging in document analysis, particularly towards automated questioned document examination.
