This paper presents a new approach to defining additive steganographic distortion in the spatial domain. The change in the output of directional high-pass filters after changing one pixel is weighted and then aggregated using the reciprocal Hölder n
A three–dimensional (3-D) broadband dual-layer multiaperature microstrip directional coupler is presented in this paper. The dual-layer, multiaperature directional coupler consists of two-layer back-to-back substrates with 15 small coupling aperture
The past decade has witnessed a remarkable interest in wireless ad hoc networks that operate without any infrastructure support. The potential for deployment of such networks exists in many scenarios ranging from civil and construction engineering,
This paper describes sound source localization (SSL) based on deep neural networks (DNNs) using discriminative training. A na¨ıve DNNs for SSL can be configured as follows. Input is the frequency-domain feature used in other SSL methods, and the str
Wavelength-selective directional couplers as
ultrafast optical differentiators
Abstract: Wavelength-selective directional couplers with dissimilar
waveguides are designed for ultrafast optical differentiation within the
femtosecond regime (corres
Objective image quality measure, which is a fundamental and challenging job in image processing, evaluates the image quality consistently with human perception automatically. On the assumption that any image distortion could be modeled as the differe
The omni-directional reflection characteristics of one-dimensional photonic crystals composed of Ta2O5/MgF2 multi-quantum well (MQW) are studied using the transfer matrix method. An omni-directional reflector consisting of three and four Ta2O5/MgF2 M
A Compact, Omni-directional, Circularly Polarized Microstrip Antenna - Presentation of an omni-directional, circularly polarized antenna using a zero-order resonator with arc-shaped stubs
