Digital Watermarking Method Based on STFT Histogram
2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2013 This paper presents a digital audio watermarking method. In the method, watermark has been represented by a form of the histogram for sound power level's distribution in time domain in certain frequency band(s). The relation of four numbers of selected bins in a histogram are changed by a rule of watermark bits assignment.

Solving multiple windowed STFT phase retrieval problems in phase and amplitude respectively
Applied Mathematics in Science and Engineering, 2022 We study the Phase Retrieval (PR) problem under the phaseless short-time Fourier transform (STFT) measurements. This paper proposes a novel algorithm named PAR to solve the STFT PR problem in phase and amplitude respectively with a milder retrieval ...

Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Integrative Zoology, EarlyView.Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...
