Fast mosaicing method based on image resizing pre-processing Open
In recent years, mosaic images have found great success thanks to the increasing development in the field of imaging as well as the technological evolution of computer systems (camera, mobile, etc.). Mosaic images are obtained by merging s…

Adoption of serious games by teachers: the analysis method of structure, interface and use Open
In this article, we determine how to facilitate the analysis of serious games so that teachers could effectively integrate them in their teaching. The aim is to identify the mechanisms that would make serious games exploitation useful. We …

A new color image encryption algorithm using multiple chaotic maps with the intersecting planes method Open
This paper proposes a new and efficient color image encryption algorithm based on multiple chaotic maps (Logistic map, Sine map, and Chebyshev map) and the intersecting planes method inside a cube. All maps were used to fill the three adja…

A New Local Descriptor Based on Strings for Face Recognition Open
This paper proposes the use of strings as a new local descriptor for face recognition. The face image is first divided into nonoverlapping subregions from which the strings (words) are extracted using the principle of chain code algorithm …

Reconstruction of three-dimensional scenes from a sequence of images of which only one is calibrated Open
In this work, we propose a method for reconstructing three-dimensional scenes from a sequence of images of which only one image is calibrated. The system is initialized by a calibrated image. The projection matrices of the other images in …

A New Image Encryption Scheme Based on Confusion-Diffusion Using an Enhanced Skew Tent Map Open
In this paper, we propose a new image encryption scheme based on confusion and diffusion for securing a color and grayscale images using an Enhanced Skew Tent Map (ESTM). Firstly, since chaotic properties are strongly related to cryptograp…

A new color image encryption algorithm based on iterative mixing of color channels and chaos Open
In this paper, we present a novel secure cryptosystem for direct encryption of color images, based on an iterative mixing spread over three rounds of the R, G and B color channels and three enhanced chaotic maps.Each round includes an affi…

A Self-Calibration Method of Zooming Camera Open
In this article we proposed a novel approach to self- calibrate a camera with variable focal length. We show that the estimation of camera’s intrinsic parameters is possible from only two points of an unknown planar scene. The projection o…
