Impact of Dehazing on Underwater Marker Detection for Augmented Reality.

Underwater augmented reality is a very challenging task and amongst several issues, one of the most crucial aspects involves real-time tracking. Particles present in water combined with the uneven absorption of light decrease the visibility in the underwater environment. Dehazing methods are used in many areas to improve the quality of digital image data that is degraded by the influence of the environment.

[Optimism or pessimism in the treatment of cerebral infarct].

The aim of the study was to analyse the effects of drug and rehabilitation treatment of cerebral stroke. Material consists of 2,500 patients with focal brain ischemia. About three-fourths (68.

[Changes in carbohydrate metabolism before and after the development of focal cerebral ischemia. III. Function of the diencephalon].

The purpose of the investigation was to assess whether the mechanism of reduced glucose tolerance in focal ischaemia of the brain can be considered a functional disorder of the regulatory brain centres or a manifestation of inadequate glucose utilization due to impaired insulin secretion. The function of centres regulating metabolic processes was tested by the i.v.

[Changes in glucose metabolism before and after the onset of focal cerebral ischemia. I. The intravenous glucose tolerance test].

In a group of 22 patients with focal ischemia of the brain and in 11 patients with cerebral arteriosclerosis and vascular hypertension the tolerance to glucose administered by the i.v. route was investigated.
