Pixelated Flesh [PDF]

open access: yesCultural Politics, 2015
The pixel and the technique of pixelating faces belong to a politics of fear and a digital aesthetics of truth that shapes public perceptions of criminality and the threat of otherness. This article draws on Paul Virilio’s account of the pixel in The Lost Dimension to analyze its specific role and operation in relation to contemporary representations ...

Surface projection for mixed pixel restoration [PDF]

open access: yes, 2009
Amplitude modulated full-field range-imagers are measurement devices that determine the range to an object simultaneously for each pixel in the scene, but due to the nature of this operation, they commonly suffer from the significant problem of mixed ...

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 ...

The Sound of Pixels [PDF]

open access: yes, 2018
We introduce PixelPlayer, a system that, by leveraging large amounts of unlabeled videos, learns to locate image regions which produce sounds and separate the input sounds into a set of components that represents the sound from each pixel. Our approach capitalizes on the natural synchronization of the visual and audio modalities to learn models that ...

Single pixel imaging at high pixel resolutions

open access: yesOptics Express, 2022
The usually reported pixel resolution of single pixel imaging (SPI) varies between 32 × 32 and 256 × 256 pixels falling far below imaging standards with classical methods. Low resolution results from the trade-off between the acceptable compression ratio, the limited DMD modulation frequency, and reasonable reconstruction time, and has not improved ...

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 ...

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 ...

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.
