Positron Emission Tomography (PET) images are considerably degraded by respiratory and involuntary motions of the patient inside the scanner, having a direct effect in a misdiagnosis. In this paper, a dedicated PET scanner with an open geometry is pr

Unlike the usual numerical FEM approach to determine the thermally affected layer during the grinding process, we propose a simple analytical approach to estimate the depth of thermal penetration. For this purpose, the one-dimensional definition of d

Depth estimation improvement in 3D integral imaging using an edge removal approach
Autor: Hector Espinos-Morato, Bahram Javidi, Filiberto Pla, Pedro Latorre-Carmona, José Martínez Sotoca
A new depth estimation method for 3D reconstruction in a synthetic aperture integral imaging framework is presented. This method removes the edges of the objects in the elemental images when the objects are in focus. This strategy aims to compensate

Publikováno v: Journal of the AirWaste Management Association (1995). 62(8)
A monitoring program based on an indirect method was conducted to assess the approximation of the olfactory impact in several wastewater treatment plants (in the present work, only one is shown). The method uses H2S passive sampling using Palmes-type
