Self Calibration of a Sonar-Vision System for Underwater Vehicles: A New Method and a Dataset.

Monocular cameras and multibeam imaging sonars are common sensors of Unmanned Underwater Vehicles (UUV). In this paper, we propose a new method for calibrating a hybrid sonar-vision system. This method is based on motion comparisons between both images and allows us to compute the transformation matrix between the camera and the sonar and to estimate the camera's focal length.

French neuropsychological procedure consensus in epilepsy surgery.

Introduction: Neuropsychological assessment is an integral component of the surgical procedure in patients with epilepsy. As no French consensus for neuropsychological assessment was available, the main goal of this work was to define French neuropsychological procedure consensus in regard to literature review.

Method: A panel of expert in neuropsychology was created within the framework of the French League Against Epilepsy.

[Superficial hemosiderosis of the central nervous system improved by corticosteroids].

Introduction: Superficial siderosis is of the Central Nervous System (CNS) is an uncommon and often disabling disorder. There is no evidence that any treatment, including removal of an identified source of bleeding, affects disease progression.

Observation: We report the case of a 49-year-old woman exhibiting progressive and various neurological disorders associating chorea, pyramidal syndrome, cerebellar ataxia, cognitive disorders and cranial nerve deficits.

[Trichloroethylene intoxication presenting with temporal seizures].

Introduction: Trichloroethylene (TCE) is extensively used as a degreasing agent in the metal industry and as a solvent for organic compounds. Its neurotoxicity (with respect to both the peripheral and central nervous systems) is now widely acknowledged.

Observation: Here, we report the case of a 32-year-old male drug addict presenting temporal seizures after "huffing" TCE (i.

Which factors predict cognitive decline in Parkinson's disease?

The study assessed cognitive decline in non-demented, non-depressed patients with well defined Parkinson's disease and determined the predictive value for cognitive decline of different motor symptoms. Motor disability was measured with the Unified Parkinson's disease rating scale, impairment in activities of daily living, levodopa test, and long term clinical follow up. Neuropsychological evaluations included modified mini mental state, fluency, Wechsler logical memory, Wisconsin card sorting test, and the Montgomery and Asberg depression rating scale.
