Polarimetric SAR Image Segmentation with B-Splines and a New Statistical Model

We present an approach for polarimetric Synthetic Aperture Radar (SAR) image region boundary detection based on the use of B-Spline active contours and a new model for polarimetric SAR data: the GHP distribution. In order to detect the boundary of a region, initial B-Spline curves are specified, either automatically or manually, and the proposed algorithm uses a deformable contours technique to find the boundary. In doing this, the parameters of the polarimetric GHP model for the data are estimated, in order to find the transition points between the region being segmented and the surrounding area. This is a local algorithm since it works only on the region to be segmented. Results of its performance are presented

Naming Our Concerns about Neuroscience: A Review of Bennett and Hacker's Philosophical Foundations of Neuroscience

Bennett and Hacker use conceptual analysis to appraise the theoretical language of modern cognitive neuroscientists, and conclude that neuroscientific theory is largely dualistic despite the fact that neuroscientists equate mind with the operations of the brain. The central error of cognitive neuroscientists is to commit the mereological fallacy, the tendency to ascribe to the brain psychological concepts that only make sense when ascribed to whole animals. The authors review how the mereological fallacy is committed in theories of memory, perception, thinking, imagery, belief, consciousness, and other psychological processes studied by neuroscientists, and the consequences that fallacious reasoning have for our understanding of how the brain participates in cognition and behavior. Several behavior-analytic concepts may themselves be nonsense based on thorough conceptual analyses in which the criteria for sense and nonsense are found in the ways the concepts are used in ordinary language. Nevertheless, the authors' nondualistic approach and their consistent focus on behavioral criteria for the application of psychological concepts make Philosophical Foundations of Neuroscience an important contribution to cognitive neuroscience

Stalker, de Andrei Tarkovski, e a mise-en-scène como forma de experiência

The present research aims to think about the film Stalker, by the Russian director Andrei Tarkovski, from the concept of experience of the philosopher Walter Benjamin. The study was based on the analysis of the film's mise-en-scène, in order to think of it as a power to break the automatism and to perceive the images as a way of "feeling" life - a concept present in the reflection text of Viktor Chklovsky Art as procedureSubmitted by José Ricardo da Rocha Cacciari ([email protected]) on 2017-10-27T22:55:44Z No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Stalker, de Andrei Tarkovski, e a Mise-en-scène cono forma de experiência.pdf: 2448360 bytes, checksum: 90f377f87116b0361920f7cd899a0cf2 (MD5)Approved for entry into archive by Karina Ramos Wagner ([email protected]) on 2017-11-06T10:46:31Z (GMT) No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Stalker, de Andrei Tarkovski, e a Mise-en-scène cono forma de experiência.pdf: 2448360 bytes, checksum: 90f377f87116b0361920f7cd899a0cf2 (MD5)Made available in DSpace on 2017-11-06T10:46:31Z (GMT).
