Recurrent neural networks (RNN) have been successfully applied for recognition of cursive handwritten documents, both in English and Arabic scripts. Ability RNNs to model context sequence data like speech text makes them a suitable candidate develop OCR systems printed Nabataean scripts (including Nastaleeq which no system is available date). In this work, we presented the results applying RNN Urdu script. Bidirectional Long Short Term Memory (BLSTM) architecture with Connectionist Temporal...

Prior studies have shown that distinguishing text generated by large language models (LLMs) from human-written one is highly challenging, and often no better than random guessing. To verify the generalizability of this finding across languages domains, we perform an extensive case study to identify upper bound human detection accuracy. Across 16 datasets covering 9 19 annotators achieved average accuracy 87.6%, thus challenging previous conclusions. We find major gaps between machine lie in...

Hyperspectral Imaging (HSI) uses large portions of the electromagnetic spectrum to obtain information from images that would be very difficult otherwise. An important task in forensic analysis documents is extract signatures for authentication. Signatures often overlap with other parts a document such as typed text or stamps and hence it retrieve them. In this work we present novel algorithm recovering hyperspectral where text, seals, stamps, images. We used pure pixel index approaches...
