FROM IMAGE CONTOURS TO PIXELS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
This paper relates to the reconstruction of digital images using their contour representations. The process involves determining the pixel intensity value which would exist at the intersections of a regular grid using the nodes of randomly spaced ...

A New Concept for Kilotonne Scale Liquid Argon Time Projection Chambers

open access: yesInstruments, 2020
We develop a novel Time Projection Chamber (TPC) concept suitable for deployment in kilotonne-scale detectors, with a charge-readout system free from reconstruction ambiguities, and a robust TPC design that reduces high-voltage risks while increasing the

A Fast Star-Detection Algorithm under Stray-Light Interference

open access: yesPhotonics, 2023
The interference caused by stray light leads to the invalid attitude of star sensors in orbit, thus affecting the attitude control of satellites. In order to overcome this problem, this paper proposes a fast star-detection algorithm with strong stray ...

Pixel Objectness

open access: yesCoRR, 2017
We propose an end-to-end learning framework for generating foreground object segmentations. Given a single novel image, our approach produces pixel-level masks for all "object-like" regions---even for object categories never seen during training. We formulate the task as a structured prediction problem of assigning foreground/background labels to all ...

Imaging properties of pixellated scintillators with deep pixels [PDF]

open access: yesSPIE Proceedings, 2014
We have investigated the light-transport properties of scintillator arrays with long, thin pixels (deep pixels) for use in high-energy gamma-ray imaging. We compared 10×10 pixel arrays of YSO:Ce, LYSO:Ce and BGO (1mm × 1mm × 20 mm pixels) made by Proteus, Inc.

Determination of optimal formats for digital image compression

open access: yesIngenius: Revista de Ciencia y Tecnología
Se concluye que independientemente de la herramienta que se utilice, es el formato de la imagen lo que influye en el tamaño final.& The objective was to determine the influence of different image formats and tools used for compression on the final ...

Relevance of two manual tumour volume estimation methods for diffuse low-grade gliomas

open access: yesHealthcare Technology Letters, 2018
Management of diffuse low-grade glioma (DLGG) relies extensively on tumour volume estimation from MRI datasets. Two methods are currently clinically used to define this volume: the commonly used three-diameters solution and the more rarely used software ...

Pixelated Semantic Colorization [PDF]

open access: yesInternational Journal of Computer Vision, 2019
AbstractWhile many image colorization algorithms have recently shown the capability of producing plausible color versions from gray-scale photographs, they still suffer from limited semantic understanding. To address this shortcoming, we propose to exploit pixelated object semantics to guide image colorization.
