Automatic ink mismatch detection for forensic document analysis
作者：
Highlights：
• Ink mismatch detection identifies if part of a note was written with a different ink.
• Apparently similar inks are automatically distinguished using spectral information.
• A novel joint sparse band selection method is proposed for ink mismatch detection.
• A new database is collected using our camera based document imaging system.
• Extensive experiments are carried out to prove our claims.
