Studio di fattibilità sul rilevamento di enfisema in immagini ottenute mediante TAC a spirale con bassa dose
Amendola T., Chimenti M., Fantini E., Tampucci M., Miniati M., Monti S.
In a previous study we developed a software able to detect anomalies in CT high definition images of the thorax, possibly related to pulmonary emphysema; in this study we evaluate the possibility of applying this software to the CT images obtained in a large scale screening. In fact, theses images have been produced by a low-dose computer tomography and are affected by a noise greater than that of previously processed images. In this study we used a photometric images analysis, which gives the amount of pixels with luminance value less than a predefined threshold, and the blob analysis, which using the same threshold detects the binary objects composed of adjacent pixels and gives up their size and location. The paper reports the results obtained according two decision thresholds: we show that the photometric analysis of low-dose CT images gives no information about the presence of pulmonary emphysema, while the blob analysis gives useful descriptors

Nanoscale Biomolecular Detection Limit for Gold Nanoparticles Based on Near-Infrared Response
D'Acunto M., Moroni D., Salvetti O.
Gold nanoparticles have been widely used during the past few years in various technical and biomedical applications. In particular, the resonance optical properties of nanometer-sized particles have been employed to design biochips and biosensors used as analytical tools. The optical properties of nonfunctionalized gold nanoparticles and core-gold nanoshells play a crucial role for the design of biosensors where gold surface is used as a sensing component. Gold nanoparticles exhibit excellent optical tunability at visible and near-infrared frequencies leading to sharp peaks in their spectral extinction. In this paper, we study how the optical properties of gold nanoparticles and core-gold nanoshells are changed as a function of different sizes, shapes, composition, and biomolecular coating with characteristic shifts towards the near-infrared region. We show that the optical tenability can be carefully tailored for particle sizes falling in the range 100-150 nm. The results should improve the design of sensors working at the detection limit.Source: Advances in Optical Technologies (Online) 2012 (2012): 278194. doi:10.1155/2012/278194

The genus invariant for Artin groups
Moroni D., Salvetti M., Villa A.
Let (W; S) be a Coxeter system, S finite, and let G_W be the associated Artin group. One has conguration spaces Y; Y_W; where G_W = PI_1(Y_W); and a natural W-covering f_W : Y --> Y_W. We consider the Schwarz genus g(f_W) of this covering, which is a natural topological in- variant of the Artin group. Let K = K(W; S) be the simplicial scheme of all subsets J subset of S such that the parabolic group W_J is finite. We introduce the class of Artin groups, which includes affine-type Artin groups, for which dim(K) equals the homological dimension of K; and we show that g(f_W) is always the maximum possible for this class of groups. Such maximum is given by dim(X_W) + 1; where X_W (subset of Y_W) is a CW-complex which has the same homotopy type. This result extends a previous result in [Deconcini Salvetti 2000] obtained for all finite-type Artin groups, with the exception of case A_n (for which see [Deconcini Procesi Salvetti 2004]).Source: ISTI Technical reports, 2012

A Knowledge Editing Service for Multisource Data Management in Remote Health Monitoring
S. Colantonio, M. Esposito, M. Martinelli, G. De Pietro, O. Salvetti
Remote Health Monitoring (RHM) programmes are being increasingly developed to face the pervasive diffusion of chronic diseases. RHM strongly relies on ICT intelligent platforms devised to remotely acquire multisource data, process these according to specific domain knowledge and support clinical decision making. However, since RHM domain is continuously evolving and the pertinent knowledge is not yet consolidated, there is a great demand for services and tools that allow the encoded knowledge to be modified and enriched. This paper presents a Knowledge Editing Service (KES), which aims at enabling clinicians to insert novel knowledge, in a controlled fashion, into an ICT intelligent platform. The solution proposed is innovative since it addresses synergistically peculiar issues related to (i) RHM knowledge format; (ii) controlled editing patterns; (iii) knowledge verification and (iv) cooperative knowledge editing. None of the existing methods and systems for knowledge authoring tackles all these aspects at the same time. A prototype of the KES has been implemented and evaluated in real operational conditions.Source: IEEE transactions on information technology in biomedicine 16 (2012): 1096–1104. doi:10.1109/TITB.2012.2215622

Decision Support for the Remote Management of Chronic Patients
Colantonio S., De Pietro G., Esposito M., Machì A., Martinelli M., Salvetti O.
Chronic diseases may cause major limitations in patients' daily living due to acute or deterioration events, which can happen more or less frequently and, often, cannot be totally relieved, causing a worsening of patients' conditions. In the last years, a strong effort is being spent in the development of intelligent ICT applications for patients' telemonitoring, aimed at maximizing the quality of life of chronic patients by means of a regular collection of information about their status and actions in a long-stay setting. In this paper, a knowledge based decision support system is presented, which is aimed at aiding clinical professionals in managing chronic patients on a daily basis, by assessing their current status, helping face their worsening conditions, and preventing their exacerbation events.Source: MobiHealth 2011 - Wireless Mobile Communication and Healthcare.

Color restoration in old photographs using dark channel processing
Kuruoglu E. E.
We propose a direct and effective method for color restoration and contrast enhancement in old images. The main idea is based on the dark channel assumption. Using this assumption with the faded old image model, we can directly estimate the degraded transmission coefficient of an old image and directly recover it to a high quality degradation-free image. Moreover, a novel average processing and dark channel processing chain method (A-D chain method) is proposed to partly avoid the side effects introduced by dark channel processing.Source: ISTI Technical reports, pp.1–13, 2012

Estimation of motion blurring direction by rotated accumulation method
Liu Y., Gao C., Kuruoglu E. E.
Motion blur is usually caused by the motion between the camera and the scene during integration time of image. And the estimation of motion blurring direction is vital to restoration. There are existing methods such as Radon and cepstrum based approach. In this paper, a Rotated Accumulation Method by selecting the minimum value of rows in frequency domain is introduced to find the motion direction. Also, it is shown that this method is more advisable than spatial based method when the motion length is relatively small or the image is blurred by noise, and more accurate comparing to Radon method.Source: ISTI Technical reports, 2012

Handwritten chinese character recognition using eigenspace decomposition
Long H., Zhang X., Kuruoglu E. E.
In this paper, we mainly describe a new approach of Handwritten Chinese Character Recognition (HCCR), which is based on eigen-character extraction. The procedure of the eigen-character extraction method is explained including initialization, eigen character extraction (or eigen spaces generation) and character recognition. Two different methods are presented to do eigen character recognition respectively. Besides, k Nearest Neighbor (kNN) is implemented to improve the recognition rate of the new approach. In the end, a comparison is made between the eigen-character extraction approach and other existing approaches through simulation based experiments. The results show that our approach has a satisfying rate and could be further improved if combined with some other methods such as elastic matching and wavelet methods.Source: ISTI Technical reports, pp.1–8, 2012

Scale invariant feature detection for object recognition in colour images
Yang S., Li Y., Kuruoglu E. E.
This paper presents a method for extracting features from color images that can be used to perform reliable matching between different views of an object or scene. We extend the concept of the feature vector given in Lowe's method to color images by defining new gradient operator or giving new feature descriptor, which result in different algorithms with different optimality in the sense of information utilization of the original color image. Generally, better algorithm optimality is coupled with higher computation complexity, which is the case in this paper. Thus, the 4 methods proposed in this paper lead to a multi-optimality and multi-complexity scheme. In practice, people can choose which method to use according to their needs and computation abilities.Source: ISTI Technical reports, pp.1–14, 2012

Epicardial fat volume assessment in cardiac CT
Coppini G., Favilla R., Moroni D., Salvetti O., D'Errico L., Salituri F., Ciardetti M., Schlueter M., Faggioni L., Coceani M., Mazzarisi A., Bianchi M., Bartolozzi C., Marraccini P.
Epicardial fat, as other visceral fat localizations, is correlated with car- diovascular disease, cardiovascular risk factors and metabolic syndrome. However, many concerns remain about the method for measuring epi- cardial fat, its regional distribution on the myocardium, as well as the accuracy and reproducibility of such measurements. At present, dedi- cated software procedures to assess epicardial fat are lacking. On the other hand, manual fat segmentation requires a huge and tedious operator intervention, which is expected to cause inaccuracy and large observer- dependent variability. The aim of this study was twofold: (1) the devel- opment of a procedure devoted to assess the volume of epicardial fat, (2) the evaluation of the related intra and inter-observer variability in CT scans, both with and without contrast medium injection.Source: International journal of computer assisted radiology and surgery (Print) 7 (2012): 40–40.
