In this paper we present the UMB-DB 3D face database. The database has been built to test algorithms and systems for analysis in uncontrolled challenging scenarios, particular those cases where faces are occluded. is composed of 1473 pairs depth color images 143 subjects. Each subject acquired with different facial expressions, partially occluded by various objects such as eyeglasses, hats, scarves hands. total number acquisitions 578. database, that freely available research purposes, could...

Hospitals and other healthcare facilities harbor a complex interplay of microbial pathogens. The correct understanding pathogens distribution evolution is therefore crucial for infections control the design effective prevention strategies. In parallel, integration cutting-edge nanotechnologies early detection monitoring these specific target considered most approach to face nosocomial infections. this context, point-of-care (POC) testing, also known as near-patient becoming increasingly...

This paper presents an innovative restoration strategy which allows for effective recognition of 3D faces, even when they are partially occluded by unforeseen, extraneous objects such as scarves, hats, glasses, and so on. First, the regions detected considering their effects on projections faces in a suitable face space; non-occluded then used to restore missing information. Any algorithm can be applied usual restored faces. led very satisfactory results test set 52 three-dimensional...

The interaction between tumor cells and activated fibroblasts determines malignant features of desmoplastic carcinomas such as rapid growth, progression towards a metastatic phenotype, resistance to chemotherapy. On one hand, can activate normal even reprogram them into CAFs through complex mechanisms that also involve soluble factors. Among them, transforming growth factor beta (TGF-β) Platelet-Derived Growth Factor (PDGF) have an established role in the acquisition pro-tumorigenic...

We have implemented a full automatic pipeline that is able to automatically detect, normalize and recognize the faces in presence of extraneous objects. The face detector uses curvature analysis, surface registration through ICP Gappy PCA classification. After detection normalization, images are restored using an occlusion algorithm followed by reconstruction. Feature extraction matching performed Fisherfaces recognition, but any state art approach may be applied. proposed system has been...

We present here a fully automated system for face detection and recognition. In scene acquired by three-dimensional laser scanner the can detect presence of human faces; faces detected are registered in canonical position then recognized. Both 3D 2D (i.e. pictorial) information provided exploited. The representation is used to normalize them. recognition step independently analyzed, producing two different scores that combined compute output system.

The authors have compared individual cancer mortality records from the file of Central Statistics Office (ISTAT) with those Cancer Registries Varese and Torino for period July-December 1976. Most diagnoses ascertained by were histologically confirmed. results showed a high degree reciprocal completeness (over 90 %) both systems (Cancer statistics) satisfactory level concordance (75 % at Varese, 70 Torino). discrepancies, concentrated in certain nosologic codes, analyzed. conclusions suggest...

Three-dimensional data generated from range scanners is usually composed of a huge amount information. Simplification and compression techniques must be adopted in order to reduce transmission or processing time allow real-time visualization. In this paper we propose an approach semantic simplification triangular meshes representing faces. The algorithm aimed preserve facial features can used especially for face recognition systems purposes. first phase detect salient regions using 3D...

A population-based survey of histologically diagnosed breast cancer was carried out among residents in Piedmont. total 5267 incident cases occurring 1979–1981 collected, corresponding to an age-standardized (on the world population) incidence rate 49.5/100,000 per year. Rates (standardized on population Piedmont 1981) were highest city Torino (112.4/100,000 year) and lowest province Cuneo (67.5), whereas other provinces they ranged between 85.3 90.0.
