Physical pixels
… Like all data structures of the computer, pixels are invisible and therefore require an output device to be seen. The physical unit of display, or physical pixel, can be any form that makes the pixel visible. Pixels are often represented as the electronically addressable phosphors of a …

Electromagnetic Printhead Core for Programming Magnetic Pixels
… The thesis also assess how the generated flux pixels, using an electromagnet, compare to those generated by permanent magnets, before offering some praxis for programmable magnetic sheets.

Handling Invalid Pixels in Convolutional Neural Networks
… convolutional layer that assumes that all input pixels are valid pixels. However, pixels added to the input through padding result in adding extra information that was not initially present. This extra information can be considered invalid. Invalid pixels can also be inside the image where they …

Liberated pixels : alternative narratives for lighting future cities
… control. The first of these explorations, Urban Pixels, presents a wireless network of individual, autonomous physical pixels that can be deployed on any surface in the city. The second, Light Bodies, reconnects with the history of lights-on-people like lanterns that travel through the city with …

Going beyond chalk to pixels : the manipulations of a technochick
This didactic CD-ROM is designed for art educators and artists who have yet to use a computer as a means for creating digital imagery. Through its multimedia interaction, users will be encouraged to try new methods and procedures for creating in a digital environment by manipulating an image from a …

Beyond pixels : exploring new representations and applications for motion analysis
… modeling of the grouping relationship of pixels and from a lack of ground-truth data. Using layers as the interface for humans to interact with videos, we build a human-assisted motion annotation system to obtain ground-truth motion, missing in the literature, for natural video sequences. …

From physiology to pixels: Resource allocation tradeoffs and noninvasive technologies for studying marine mammals
Long-term energy management shapes survival and reproductive success across mammals. Using the exceptional >60-year Weddell seal (Leptonychotes weddellii) demographic study in Erebus Bay, Antarctica, this dissertation links individual physiological traits to lifetime reproductive output in a …

Beyond the pixels: learning and utilising video compression features for localisation of digital tampering.
… to derive compression features directly from the pixels of video frames. It is then shown that these features can be readily used to detect inauthentic video content with good accuracy across multiple different video tampering techniques. Moreover, the ability to explain these features allows …

Terahertz beam-steering imager using a scalable 2D-coupled architecture and multi- functional heterodyne pixels
The topic covered by this thesis is the project of designing a terahertz imager chip on nowadays commercialized mature silicon platform. In the project, we developed the design method of a multi-functional heterodyne pixel and a scalable array architecture. The pixel is a compact electromagnetic …

A Critical Inquiry: Paintbrush to Pixels; Developing Paradigms In the production and consumption of New Media Art.
Art represents our culture, and our current culture is largely dependent on technology. However, artworks created and exhibited with digital technologies have not been as perceptible so far within contemporary arts institutions as traditional analogue art forms. This thesis instigates a critical …

Toward a multi-scale participatory urban policymaking platform : co-designing Mass Transit using LEGO bricks, open data, and interactive pixels
Rapid urbanization and industrialization around the globe have brought urban policymakers complex challenges such as chronic congestion, environmental pollution and socio-economic inequalities. With the rising adoption of and sophistication of social media and personal electronic devices, citizens …

Geographic Information System Topographic Factor Maps for Wildlife Management
… model, called "exclusionary", excluded those pixels with landform characteristics different from the known squirrel pixels based on histogram analyses. Logistic regression was used to create the other 2 models. Each model resulted in an image of pixels considered equivalent to the known …

A noise detection, noise-motion separation and a cancer recognition theory and algorithm
… the noise. The difference between corresponding pixels subject to one type of noise, of two frames, has mean vector equal to (0,0,0), and variance covariance matrix with relatively small variances, for the (R, G, B) difference values. The other type of noise is a result of disturbance of the …
