In this paper, we present a robust approach of automatic detection and recognition of road signs in national roads, starting from the images resulting from a video stream taken by a camera embarked on a vehicle. Our approach is composed of three main phases: the first phase is to extract video stream images containing a circle or a triangle. This extraction(More)
The adoption of cloud computing is accelerating among health care providers, as they realize the limitations of traditional systems of computerized medical file. Many obstacles must be overcome, however, with regard to respect for privacy and patient safety. In order to ensure the respect for privacy, an encryption of data is required. An encryption that(More)
This paper introduces two decoders for binary linear codes based on Metaheuristics. The first one uses a genetic algorithm and the second is based on a combination genetic algorithm with a feed forward neural network. The decoder based on the genetic algorithms (DAG) applied to BCH and convolutional codes give good performances compared to Chase-2 and(More)
