Full parallax three-dimensional display from Kinect v1 and v2

2016

We exploit the two different versions of Kinect, v1 and v2, for the calculation of microimages projected onto integral-imaging displays. Our approach is based on composing a three-dimensional (3-D) point cloud from a captured depth map and RGB information. These fused 3-D maps permit to generate an integral image after projecting the information through a virtual pinhole array. In our analysis, we take into account that each of the Kinect devices has its own inherent capacities and individualities. We illustrate our analysis with some imaging experiments, provide the distinctive differences between the two Kinect devices, and finally conclude that Kinect v2 allows the display of 3-D images …

Piano col colore… !

2012

Il capitolo del volume Città, Intonaci, Colore, tratta il tema dei Piani del Colore in Italia. La trattazione presenta le riflessioni che si sviluppano in Italia sin dagli anni Settanta del XX secolo e che condurranno all'elaborazione dei cosidetti "piani del colore". Il saggio esamina i contenuti dei piani di molte città italiane e mostra gli esiti degli interventi sulle facciate delle architetture nei centri storici. The chapter of the book deals with the subject of the Color Plans diffused in Italy. The discussion presents the reflections that develop in Italy since the seventies of the twentieth century and that will lead to the processing of so-called "Color plans". The essay examines …

Does transvaginal color Doppler sonography differentiate between developing and involuting ectopic pregnancies?

1995

The objective of this study was to assess the addition of transvaginal color Doppler imaging to transvaginal ultrasonography and beta-human chorionic gonadotropin values to differentiate between developin and involuting ectopic pregnancies. Forty surgically confirmed ectopic pregnancies were classified into developing or involuting according to histopathologic findings. Results were compared retrospectively with the plasma beta-human chorionic gonadotropin values as well as the resistive index and pulsatility index obtained in corpora lutea and peritrophoblastic flow in serial examinations. Student's t-test was used for comparison of means. Logistic regression analysis was applied to predic…

Real-Time Temporal Superpixels for Unsupervised Remote Photoplethysmography

2018

International audience; Segmentation is a critical step for many computer vision applications. Among them, the remote photoplethys-mography technique is significantly impacted by the quality of region of interest segmentation. With the heart-rate estimation accuracy, the processing time is obviously a key issue for real-time monitoring. Recent face detection algorithms can perform real-time processing, however for unsupervised algorithms, i.e. without any subject detection based on supervised learning, existing methods are not able to achieve real-time on regular platform. In this paper, we propose a new method to perform real-time un-supervised remote photoplethysmograhy based on efficient…

Plasma cell-free DNA in diagnostic KRAS mutation testing

2015

Epidermaalisen kasvutekijän reseptorin (EGFR) monoklonaalisia vasta-aineita (mAb) käytetään apuna metastaattisen kolorektaalisyövän (mCRC) hoidossa. Aktivoivat mutaatiot KRAS- ja NRAS-onkogeeneissä tekevät syöpäsolut vastustuskykyisiksi anti-EGFR-vasta-aineille, ja tästä syystä tuumorit tulee genotyypittää ennen hoidon aloittamista. Kudosbiopsian ottaminen on kuitenkin invasiivinen toimenpide, eikä näyte välttämättä edusta kattavasti syövän kaikkien solupopulaatioiden geneettisiä muutoksia. Verenkierron solunulkoisen DNA:n (cfDNA) on havaittu sisältävän maligneista soluista lähtöisin olevia onkogeenisiä mutaatioita, ja se voi olla hyvä vaihtoehtoinen tuumoriperäisen DNA:n lähde. Kehitimme j…

Association of mechanical bowel preparation with oral antibiotics and anastomotic leak following left sided colorectal resection: an international, m…

2018

INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…

The role of Doppler ultrasonography in determining the proper surgical approach to the management of varicocele in children and adolescents

2006

In a study from Italy, colour-Doppler ultrasonography was a reliable diagnostic tool in the preoperative assessment of patients with varicocele. The authors also found that it helped to distinguish those who could be treated laparoscopically from those who should be treated by microsurgical subinguinal ligature. OBJECTIVE To investigate whether colour Doppler ultrasonography (CDUS) is a reliable diagnostic tool for selecting patients with varicocele to undergo either laparoscopy or open microsurgical subinguinal ligation. PATIENTS AND METHODS In a 3-year period, 42 boys affected by left varicocele were evaluated before surgery by inguinal and scrotal CDUS. Using this method it was possible …
