Reconsidering the substance of digital video from a Sadrian perspective [PDF]
, 2020 The digitisation process is debated as video’s deficiency, where pixels are conceived as isolated fragments without an existential link to the source image.

International Journal of Applied Earth Observation and Geoinformation, 2021 A timely and detailed crop-specific land cover map can support many agricultural applications and decision makings. However, in-season crop mapping over a large area is still challenging due to the insufficiency of ground truth in the early stage of a ...

Temperature Sensors Integrated into a CMOS Image Sensor
Proceedings, 2017 In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is

Cultural 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 ...

Single-pixel ptychography [PDF]
Optics Letters, 2021 Ptychography is a predominant non-interferometric technique to image large complex fields but with quite a narrow working spectrum, because diffraction measurements require dense array detection with an ultra-high dynamic range. Here we report a single-pixel ptychography technique that realizes non-interferometric and non-scanning complex-field imaging

SpatialTracker: Tracking Any 2D Pixels in 3D Space [PDF]
Computer Vision and Pattern RecognitionRecovering dense and long-range pixel motion in videos is a challenging problem. Part of the difficulty arises from the 3D-to-2D projection process, leading to occlusions and discontinuities in the 2D motion domain.

Vertical-junction photodiodes for smaller pixels in retinal prostheses
Journal of Neural Engineering, 2021 Objective. To restore central vision in patients with atrophic age-related macular degeneration, we replace the lost photoreceptors with photovoltaic pixels, which convert light into current and stimulate the secondary retinal neurons.

Switching dynamics of spatial solitary wave pixels [PDF]
, 1993 Separatrices and scaling laws in the switching dynamics of spatial solitary wave pixels are investigated. We show that the dynamics in the full model are similar to those in the plane-wave limit.
