Multiple-Image Hiding by Using Single-Shot Ptychography in Transform Domain

IEEE Photonics Journal, 2017
A practical method using single-shot ptychographic imaging (SPI) in the transform domain is proposed for multiple-image hiding. The excellent compressibility of SPI can bring high multiplexing capacity and imperceptibility to the proposed multiple-image ...

Imperceptible of Watermarking in Digital Image Based Singular Value Decomposition

Makara Seri Sains, 2006
Watermarking is a commonly used technique to protect digital image from unintended used such as counterfeiting. This paper will address one of the techniques to embed a watermark to digital image which is based on the singular value decomposition.

An Adaptive Embedding Strength Watermarking Algorithm Based on Shearlets’ Capture Directional Features

Mathematics, 2020
The discrete wavelet transform (DWT) is unable to represent the directional features of an image. Similarly, a fixed embedding strength is not able to establish an ideal balance between imperceptibility and robustness of a watermarked image. In this work,

Towards a Wearer-Centred Framework for Animal Biotelemetry [PDF]

, 2016
The emerging discipline of Animal-Computer Interaction (ACI) aims to understand the relation between animals and technology in naturalistic settings, to design technology that can support animals in different contexts and to develop user-centred research

Imperception

Terrain
Depuis 2012, un différend épisté- mologique oppose Aparecida Vilaça et Tanya Luhrmann au sujet du statut à accorder à l’invisible. Dans cet article, nous défendons l’idée selon laquelle ce genre de débat est mieux rendu si on l’aborde à partir de la catégorie d’« imperception » : on désigne par là le rapport que nous entretenons à ce qu ...

Balancing Transferability and Imperceptibility for Adversarial Attacks [PDF]

Jisuanji kexue
Data-driven deep learning models face the problem of well-designed adversarial attacks due to their inability to cover all possible sample data.The existing main Lp-norm perturbation attack methods based on RGB pixel space have achieved great attack ...
