The steganography is the art of hidden; its main aim is to pass unnoticed data in another data. There are many types of data that used in steganography, such as message, image, and video. In this work, we are interested in hiding a message inside an image. Our work focuses on the study of three approaches based on least significant bit (LSB) techniques that mean put the bits of the message in the...
In medical field, deformable image registration is a critical task, it aims at deforming one image so that each point maps to a corresponding point in another image. The main component of deformable image registration is the similarity measure that is maximized during the optimization process. In this paper, we evaluate the effect of the choice of similarity measures for B-spline deformable registration...
This paper introduces compact music-inspired computing. We propose a music-inspired optimization technique with minimal computational cost. The aim is to reduce the memory storage capacity required by the classical harmony search algorithm (HSA) while improving their performance. Therefore, we propose three compact harmony search algorithms. The main idea is to represent the harmonies stored in the...
Compact evolutionary algorithms (cEAs) are optimization algorithms that require minimal computational cost. They do not require the storage of the population but they represent it by a distribution function. In all known cEAs, normal probability of density function (N-PDF) is used. In this paper, in order to improve the performance of cEAs and to reduce their complicity, we propose a more simple distribution...
Every TTS system must be able to convert graphemic strings into phonological representations for the purpose of pronouncing the input text. Phonetisaurus is a WFST (weighted finite-state transducer)-driven grapheme-to-phoneme (g2p) framework suitable for rapid development of high quality g2p systems. In this paper we present this fully data-driven technique, the preliminary investigations of the applicability...
The paper presents a new multi-controllers approach with H∝ control applied to control a manipulator robot wrist (Staubli RX-90). A brief description of process and linear mathematical modeling of the process. Principle of multi-controllers approach of control is briefly presented. Our new proposals concerning the type of the controllers used in the multi-controller approach of control and which are...
