On the Robustness of Semantic Segmentation Models to Adversarial Attacks.

Deep Neural Networks (DNNs) have demonstrated exceptional performance on most recognition tasks such as image classification and segmentation. However, they have also been shown to be vulnerable to adversarial examples. This phenomenon has recently attracted a lot of attention but it has not been extensively studied on multiple, large-scale datasets and structured prediction tasks such as semantic segmentation which often require more specialised networks with additional components such as CRFs, dilated convolutions, skip-connections and multiscale processing.

ROAM: A Rich Object Appearance Model with Application to Rotoscoping.

Rotoscoping, the detailed delineation of scene elements through a video shot, is a painstaking task of tremendous importance in professional post-production pipelines. While pixel-wise segmentation techniques can help for this task, professional rotoscoping tools rely on parametric curves that offer the artists a much better interactive control on the definition, editing and manipulation of the segments of interest. Sticking to this prevalent rotoscoping paradigm, we propose a novel framework to capture and track the visual aspect of an arbitrary object in a scene, given an initial closed outline of this object.

The space psychological research in the Czech Republic.

The paper informs about the history of psychological space research in Czechoslovakia and in the Czech Republic. The origins of aerospace research date back to the 1970s and were related to Interkosmos program. The paper details research carried out within its frame, focusing namely on the study of astronaut's personality and his/her psychological condition, ability of operators to work, impact of zero gravity and G-force, and study of small isolated groups.

Life frustration in cardiovascular patients.

A different structure of values and life frustrations was observed in subjects with psychosomatic disease than in healthy subjects. The subjects with ischemic disease were affected mostly in the sphere of working and existential needs, whereas their family and social relations were not disturbed, and they were not frustrated in the sphere of material needs, either. On the other hand subjects with ulcer disease felt much more affected in social relations and in primary material needs.

Structure of life frustrations in subjects prone to ischemic heart disease.

Men, exhibiting risk factors of ischaemic heart disease (hypertension, family history, smoking, diabetes, retinal angiopathy, hypercholesterolaemia) reported to be less frustrated practically in all spheres of life than non-risk men. In women the overall difference was less conspicuous but the structure of frustrations somewhat differed. The IHD-prone women were more frustrated in the sphere of material needs and of assessment of their own health, which suggests that in them a certain feeling of illness is yet developing.
