Wavelet-based Entropy Measure for Rate-Distortion Optimization in Image Coding
Authors: Garcia-Alvarez J. , Führ H. , Castellanos-Domínguez G. 
Published: August 2010

Wavelet-based Entropy Measure for Rate-Distortion Optimization in Image CodingA novel method for calculation of the entropy measure in wavelet space is proposed. This perceived-based entropy measure uses a Second Order Model entropy estimator, in which the occurrence of neighbors is considered in formulation. It has the intention to allow the implementation of a more suitable measure in coding processes and a relationship between the metric and the description of perceptual features. This method is used for the Rate-Distortion optimization in order to improve the bit-allocation coding algorithm, demonstrating that the wavelet-based entropy estimates a truncation step close to the target rate. The hypothesis is founded in the effect of distortion on the coefficient allocation. Because entropy measure is a close approximation of the conditional probability of image in multi-resolution space, it provides an adequate representation for the information of aDetailfeature. A definition of Detail-based homogeneity variance criteria is used for the information quantity - wavelet representation space, in order to find the image that fits a given Quality Level criteria. Experimental results are obtained for artificial and natural databases.
Autofocusing with the help of orthogonal series transforms
Authors: Śliwiński Przemysław 
Published: August 2010

Autofocusing with the help of orthogonal series transformsAn autofocus algorithm employing orthogonal series expansions is proposed. Several instances of the generic algorithm, based on discrete trigonometric, polynomial and wavelet series, are reviewed. The algorithms are easy to implement in the transform coders used in digital cameras. Formal analysis of the algorithm properties is illustrated in experiments. Some practical issues are also discussed.
Random Approach to Optimization of Overlay Public-Resource Computing Systems
Authors: Chmaj Grzegorz , Walkowiak Krzysztof 
Published: August 2010

Random Approach to Optimization of Overlay Public-Resource Computing SystemsThe growing need for computationally demanding systems triggers the development of various network-oriented computing systems organized in a distributed manner. In this work we concentrate on one kind of such systems, i.e. public-resource computing systems. The considered system works on the top of an overlay network and uses personal computers and other relatively simple electronic equipment instead of supercomputers. We assume that two kinds of network flows are used to distribute the data in the public-resource computing systems: unicast and peer-to-peer. We formulate an optimization model of the system. After that we propose random algorithms that optimize jointly the allocation of computational tasks and the distribution of the output data. To evaluate the algorithms we run numerical experiments and present results showing the comparison of the random approach against optimal solutions provided by the CPLEX solver.

Combining Popular Game Consoles and OSGi to Investigate Autonomous In-The-Field Biomedical Data Acquisition and ManagementThe need and interest in conducting biomedical research outside the traditional laboratory is increasing. In the field testing such as in the participant's home or work environment is a growing consideration when undertaking biomedical investigation. This type of research requires at a minimum semi-autonomous computer systems that collect such data and send it back to the laboratory for processing and dissemination with the smallest amount of attendance by the participant or even the experimenter. A key aspect of supporting this type of research is the selection of the appropriate software and hardware components. These supporting systems need to be reliable, allow considerable customizability and be readily accessible but also able to be locked down. In this paper we report a set of requirements for the hardware and software for such a system. We then utilise these requirements to evaluate the use of game consoles as a hardware platform in comparison to other hardware choices. We finish by outline one particular aspect of the supporting software used to support the chosen hardware platform based on the OSGi framework.

Published: August 2010

Development of optical fiber technology in PolandOptical fiber technology is an important branch of science and technology, but also economy. Together with related disciplines it creates wider areas like optoelectronics and photonics. Optical fiber technology is developed in this country rather dynamically, proportionally to the available funds designed locally for research and applications. Recently this development was enhanced with considerable funds from European Operational Funds Innovative Economy POIG and Human Capital POKL. The paper summarizes the development of optical fiber technology in Poland from academic perspective during the period of last 2-3 years. Probably the digest is not very not full. An emphasis is put on development of optical fiber manufacturing methods. This development was illustrated by a few examples of optical fiber applications.
Traumatic Dislocation of LASIK Flaps 4 and 9 Years After Surgery
Authors: Kim Hyunjin Jane , Silverman Cary M. 
Published: August 2010

Purpose:To report two patients who developed a corneal flap dehiscence 4 years and 9 years after LASIK, respectively, following trauma during routine domestic activities.Methods:Retrospective chart review of two patients. Clinical presentation, mechanism of injury, treatment, complications, and outcome were studied. A review of published cases in the English literature on late onset flap dislocation was performed.Results:Case 1 involved a 30-year-old man who presented 4 years after LASIK, after his eye was struck with a piece of wood from a window trim. Examination showed uncorrected visual acuity (UCVA) of 20/25 and flap displacement, creating a fold at the superior edge. Because the injury involved the periphery of the flap, the patient was treated medically only. Final UCVA was 20/20−1with a persistent fold. Case 2 involved a 29-year-old man who dislocated his flap after being hit with a dog’s paw 9 years after LASIK. Uncorrected visual acuity was count fingers, and a complete flap dislocation that was folded at the hinge with 30% epithelial ingrowth was noted. Immediate surgical removal of the epithelium from the stromal bed was completed and a bandage contact lens was used along with topical medication. Final UCVA was 20/25, with no complications.Conclusions:Flap dehiscence is a rare, late complication of LASIK. Case 1 is the second report of flap dislocation treated medically only and case 2 is the latest report. Tangential force applied to the flap during routine activities of life can result in flap displacement for up to 9 years after LASIK.

Purpose:To evaluate the visual outcomes, predictability, and planarity of four types of 60-kHz femtosecond laser–assisted LASIK flaps: 90, 100, 110, and 120μm.Methods:This randomized, prospective, interventional, comparative trial was performed at a tertiary care facility. Two hundred forty eyes with a calculated residual bed thickness >300μm (at 120-μm flap thickness and subjective refraction) were randomized into four flap thickness groups to undergo femtosecond laser–assisted LASIK. Pre- and postoperative assessment included uncorrected visual acuity, best spectacle-corrected visual acuity (BSCVA), and refraction. Flap thickness was assessed by anterior segment optical coherence tomography on 28 points per flap at 1-month follow-up. Three new indices were devised to assess the predictability and planarity.Results:The baseline parameters were matched. Postoperative vision and refractive outcome were similar in the four groups (P>.05, analysis of variance). The achieved flap thickness was different at each measured point among the groups (P<.05) with standard deviations ranging from ±3.2 to ±7.3μm. The predictability and planarity were satisfactory in all four groups, although the indices were slightly better in the 110-μm and 120-μm groups. No loss of BSCVA or flap complications occurred in the four groups.Conclusions:The study demonstrated that all four flap thicknesses are relatively uniform in predictability and clinical outcomes.

Does landscape composition alter the spatiotemporal distribution of the pine processionary moth in a pine plantation forest?
Authors: Samalens Jean‐Charles , Rossi Jean‐Pierre 
Published: August 2010

AbstractLandscape composition and physiognomy affect community structure and species distribution across space and time. The pine processionary moth (PPM) (Thaumetopoea pityocampaDen. & Schiff., Lepidoptera, Notodontidae) is a common pine defoliator throughout southern Europe and Mediterranean countries. We surveyed the spatiotemporal distribution of the PPM in a pine plantation forest in southwestern France and used the density of the winter nests as a proxy for population density. The study spanned 4 years (2005–2008) and showed a high temporal variability in nest density. We found a strong edge effect with nest densities at stand edges more than twice as large as within‐stand densities. At the landscape scale, the spatial distribution of the moth exhibited a significant spatial autocorrelation in 3 out of 4 years of our study. The spatial scales of the autocorrelation ranged from ca. 2 km to more than 22 km. We found a positive correlation between spatial distributions corresponding to certain sampling years, but the relationship was not systematic. Landscape configuration appeared to be an important driver of the PPM spatial pattern. Bivariate Moran'sIcorrelograms showed that patch richness density as well as the percentage of local landscape covered by various land uses were correlated with population density. The study showed that accounting for landscape characteristics may be important in order to understand forest insect pest distribution, even in cases where the host species is abundant and homogeneously distributed throughout the study area, e.g., pure plantation forests.
