Nowadays, information fusion constitutes a challenging research topic. Our study proposes to achieve the fusion of several knowledge sources. This, in order to detect the esophagus inner wall from ultrasound medical images. After a brief description of information fusion concepts, we propose a system architecture including both model and data fusion. The(More)
In this paper, we propose a new semantic distortion control method for database watermarking. It is based on the identification of the semantic links that exist in-between attribute's values in tuples by means of an ontology. Such a database distortion control provides the capability for any watermarking scheme to avoid incoherent records and consequently(More)
Nowadays, information fusion constitutes a challenging research topic. Our study proposes to achieve the fusion of several knowledge sources, in order to detect the aorta artery, in ultrasound slices of the esophagus area. After a brief description of information fusion concepts, we propose a system architecture including both model and data fusion. Two(More)
—Carrier aggregation (CA) is one of the key features of LTE-Advanced. On one hand it allows to boost the system capacity and on the other hand it enables dynamic spectrum access, such as licensed assisted access (LAA) and licensed shared access (LSA). Efficiently exploiting CA is however not a trivial task; the main challenges are scheduling, load(More)
abstract In addition to the source coding VQ artifacts, which usually introduce visible distortions in the form of block effect and staircase noise along the edges, the VQ indexes encoded bit stream is vulnerable to transmission errors resulting in a visually annoying artifact having an impulse block noise in the reconstructed images. In this paper, we(More)
