A Discussion on the Accuracy and Performance of Local Stereo Algorithms for Stereo Correspondence

Stereo vision aims at inferring 3D information from two images of the same scene simultaneously acquired from two different viewpoints. Due to the large number of application scenarios that can take advantage of 3D information, this topic received a lot of attentions in the last decades. In this paper we\u2019ll focus our attention on recent local state of the art algorithms that adapttheir supports to image content discussing their accuracy and performance

EFFICIENT AGGREGATION VIA ITERATIVE BLOCK-BASED ADAPTING SUPPORT-WEIGHTS

Local stereo matching algorithms based on adapting-weights aggregation produce excellent results compared to other lo- cal methods. In particular, they produce more accurate results near disparity edges. This improvement is obtained thanks to the fact that the support for each pixel is accurately deter- mined based on information such as colour or spatial distance. However, the computation of the support for each pixel results in computationally complex algorithms, especially when us- ing large aggregation windows. Iterative aggregation schemes are a potential alternative to using large windows. In this paper we propose a novel iterative approach for adapting- weights aggregation which produces better results and out- performs most previous adapting-weights methods

Ethical principles in occupational therapy intervention

For 2,500 years, the medical profession has created a body of ethical principles. Adapting to differeft historical and sociological circumstances, it has driven the practice of health professionals and constitutes a compilation of the rights and duties of doctors and patients.These principles represent the embryo of an emergening human science known as Bioethics. From the impulse of the scientific paradigm, a set of tasks and cares that were included in what was called charity started to be classified in a group of new proffesions devoted to the "methodical" care of patients and the underprivileged. Several new professions sprung up, including Occupational Therapy. From then on, the practice of the occupational therapist has remained protected by ethical principles that have traditionally monitored and driven the medical practice.This article first summarizes the historical evolution of the different ethical codes used by health professionals, emphasizing those aspects with a greater influence in the configuration of the ethical codes connected with occupational therapy.Secondly, we analyse the way occupational therapy has integrated the ethical principles of the medical practice in its own intervention. The main ethical guidelines used in the field are the ones proposed by the American Association of Occupational Therapy (AOTA), the World Federation of Occupational Therapists (WFOT), and the Council of Occupational Therapists for the European Countries (COTEC).Finally, we point out some of the difficulties and bioethcal challenges faced by occupational therapist

Interaction of engineered surfaces with the living world: Ion implantation vs. osseointegration

The reaction of living tissues to foreign materials is a highly complex process that currently is insufficiently understood. Nevertheless, if specific reactions are to be promoted, this understanding is highly valuable and thus a significant research effort is being devoted to this issue. Typically, when a biomaterial is inserted in living tissue, proteins and other bio-molecules will adsorb to the surface. As this protein layer will mediate the interaction of the biomaterial with the living world, the consequent reactions will be highly dependant on this very first stage. Furthermore, different materials, i.e. surfaces, typically elicit a very different tissue response. It is commonly admitted that the primary adsorption depends heavily on the surface chemistry, surface topography and surface physical characteristics. Interactions between surface micro-topography and living cells have been widely studied, but protein specific reactions versus nano-topography have been barely explored. Ion beam modification of surfaces, which affect these key properties, can therefore be (i) a powerful tool to advance in the understanding of these nanoscale phenomena and (ii) useful as an industrial treatment of high value added medical devices. This work will explore the application of ion beam based surface treatments to cause specific reactions in hard tissue regeneration. A variety of in vitro and in vivo results are presented corresponding to ion implantation treatments promoting '' osseointegration '' or intimate binding between the biomaterial and the living tissue, without any soft tissue interlayer, and an overview of the mechanism behind is offered, i.e. among other behaviour of osteoblasts, signalling proteins as the integrins, nanotopographic parameters.Basque Government, Department of Industry, project ref.

Bone cell adhesion on ion implanted titanium alloys

The authors have previously reported than ion implantation can have a significant effect on osseointegration of an implant, specially when the latter is introduced in areas of poorer bone density. These results indicate that this process is particularly suited for implant devices introduced in elderly patients or in those regions that have a poor quality of bone. The aim of this work is directed to study osteoblast adhesion on Ti alloy surfaces with different ion implantation treatments, so osseoconductive properties of several surfaces can be assessed. Polished discs of Ti–6Al–4V and Ti CP GR1 titanium alloy have been prepared and ion implanted with different species and parameters (dose and energy). Afterwards, the samples have been sterilized by UV light, inoculated with 1.5×105 human bone cells and incubated during 4 h at 37 C and 5% CO2 atmosphere. Then, once fixed and rinsed, image analysis has been used to quantify the number of cells attached to the Ti discs. On a second round of tests, cell proliferation tests have been conducted during 24, 48, 144 and 192 h, respectively. Furthermore, surface analysis techniques (e.g. AFM) have been applied to learn about the qualitative behavior, i.e. morphology, of the attached cells. Cell attachment has shown to be highly sensitive to ion implantation parameters. Although some quantitative differences have been observed, the more significant differences were qualitative. AFM analysis has shown that the star-shaped bone cells attached spread more and occupied larger surfaces like in osseointegration prone surfaces, most probably due to extracellular matrix synthesized around them, while other surfaces showed mainly large and narrow shaped or round shaped bone cells often with great cellular nucleus in the middle of the cells and little extracellular matrix around. So, ion implanted surfaces that facilitate osseointegration have been identified, in terms of initial bone cell attachment quality, where although the number of attached cells were not necessarily always larger, they tended to occupy wider areas with healthier cells.Basque Government (ETORTEK MAAB); Spanish Ministry of Science of Technology-CDTI (Neotec Ref. 20020327
