Reversible data hiding for encrypted image based on adaptive prediction error coding

open access: yesIET Image Processing, 2021
Reversible data hiding (RDH) is a useful technique of data security. Embedding capacity is one of the most important performance of RDH for encrypted image.

A Quasi-Isometric Embedding Algorithm [PDF]

open access: yesPattern Recognition and Image Analysis, 2019
The Whitney embedding theorem gives an upper bound on the smallest embedding dimension of a manifold. If a data set lies on a manifold, a random projection into this reduced dimension will retain the manifold structure. Here we present an algorithm to find a projection that distorts the data as little as possible.

Algorithm-level approximation for fast (or not) embedded stereovision algorithm [PDF]

open access: yesProceedings of the 18th International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation, 2018
Because of the growing concern towards the energy consumption of embedded devices, the quality of an application is now considered as a new tunable parameter during the implementation phase. Approximations are then deliberately introduced to gain performance. Nevertheless, when implementing an approximate computing technique, quality deteriorations may

Parameterized Algorithms for Book Embedding Problems [PDF]

open access: yesJournal of Graph Algorithms and Applications, 2019
A $k$-page book embedding of a graph $G$ draws the vertices of $G$ on a line and the edges on $k$ half-planes (called pages) bounded by this line, such that no two edges on the same page cross. We study the problem of determining whether $G$ admits a $k$-page book embedding both when the linear order of the vertices is fixed, called ${\rm F{\small IXED}

Complex Permittivity Determination from Measured Scattering Parameters of TEM Waveguides [PDF]

open access: yes, 2011
This paper addresses the deembedding of the propagation function of waveguides from the scattering responses of setups composed of TEM waveguides terminated by launchers that introduce generic discontinuities.

Virtual Network Mapping Mechanism Based on k Shortest Path Algorithm Optimization and Load Balance [PDF]

open access: yesJisuanji gongcheng, 2018
As the existing nodes and links of local areas are overweight,the phenomenon of packet jitter and resource waste generates when packets transmits between nodes and adjacent links.A virtual network embedding algorithm is designed for load balancing of the

A simple NWA calibration algorithm based on a transfer standard [PDF]

open access: yes, 1997
A new two-port network analyzer (NWA) calibration technique is here presented. It uses a single two-port transfer standard plus a known reflectance to perform the calibration process.
