Noise-optimal capture for high dynamic range photography
No full textTaking multiple exposures is a well-established approach both for capturing high dynamic range (HDR) scenes and for noise reduction. But what is the optimal set of photos to capture? The typical approach to HDR capture uses a set of photos with geometrically-spaced exposure times, at a fixed ISO setting (typically ISO 100 or 200). By contrast, we show that the capture sequence with optimal worst-case performance, in general, uses much higher and variable ISO settings, and spends longer capturing the dark parts of the scene. Based on a detailed model of noise, we show that optimal capture can be formulated as a mixed integer programming problem. Compared to typical HDR capture, our method lets us achieve higher worst-case SNR in the same capture time (for some cameras, up to 19 dB improvement in the darkest regions), or much faster capture for the same minimum acceptable level of SNR. Our experiments demonstrate this advantage for both real and synthetic scenes.Natural Sciences and Engineering Research Council of Canada (NSERC).

O problema da estabilidade na justiça como equidade: da teoria moral à defesa de uma concepção política
Full text linkTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2013.A presente tese investiga como se apresenta o problema da estabilidade social nas principais obras do filósofo John Rawls, com destaque para a sua problematização em Uma teoria da justiça e O liberalismo político. O objetivo é mostrar que a questão da estabilidade já se apresenta desde o início da obra de 1971, tendo um papel significativo na compreensão da justiça como equidade que, naquela obra, é interpretada a partir da perspectiva de uma teoria moral e, posteriormente, passa a ser defendida como uma concepção política. Na medida em que o problema da estabilidade é desenvolvido, mais objetivamente, na terceira parte de Uma teoria da justiça, que é, justamente, alvo de fortes críticas, incluindo a autocrítica rawlsiana, uma parcela significativa do trabalho dedica-se à análise dos principais aspectos desse texto. O propósito da tese é mostrar a importância da argumentação desenvolvida naquela parte da obra para a compreensão do conjunto da teoria da justiça como equidade, defendendo, inclusive, que as condições para a estabilidade se mantém e são complementados nas obras posteriores, em que as principais mudanças em relação a essa questão estão relacionadas à interpretação da ideia de sociedade bem ordenada e o acréscimo da ideia de consenso sobreposto. Em consequência, a questão da estabilidade passa a ser apresentada a partir da perspectiva de uma concepção política liberal, que pretende buscar o apoio de todos os cidadãos, encontrando-se submetida a razão pública dos mesmos. As características das sociedades democráticas e o pluralismo permanente a elas associado são tomados como os principais elementos para se pensar essa concepção de justiça capaz de garantir a estabilidade social. Nesse sentido, enfatiza-se que a preocupação fundamental do filósofo em relação ao problema da estabilidade é de tornar a justiça como equidade aceitável para os cidadãos de maneira que eles próprios possam justificar, considerada a sua autonomia. Abstract : The present thesis investigates how the problem of social stability is presented in the philosopher John Rawls? main works, with emphasis on his problematization in A Theory of Justice and Political Liberalism. The objective is to show that the question of stability is already presented from the beginning of the 1971 work, having a significant role in the understanding of justice as fairness, which, in that work, is interpreted from the perspective of a moral theory, and later, came to be defined as a political conception. As the issue of stability is developed, more objectively, in the third part of A Theory of Justice, which is, precisely, subject of strong criticism, including Rawlsian self-criticism, a significant part of the work is dedicated to the analysis of the main aspects of this text. The thesis purpose is to show the importance of the arguments developed in that part of his work, in order to understand the whole theory of justice as fairness, even advocating that the conditions for stability remain and are supplemented in his later works, in which the main changes, regarding this issue, are linked to the interpretation of the well-ordered society?s idea and the addition of the overlapping consensus idea. Consequently, the question of stability starts to be presented from the perspective of a liberal political conception, which intends to seek the support of all citizens, finding itself subjected to their public reason. The characteristics of democratic societies and the permanent pluralism associated with them are taken as the main elements to think about this concept of justice, capable of ensuring social stability. In this sense, it must be emphasized that the fundamental concern of the philosopher in relation to the stability problem is to make justice as fairness acceptable to citizens, so that they themselves can justify, considered their autonomy
Search-and-replace editing for personal photo collections
Full text linkWe propose a new system for editing personal photo collections, inspired by search-and-replace editing for text. In our system, local edits specified by the user in a single photo (e.g., using the “clone brush” tool) can be propagated automatically to other photos in the same collection, by matching the edited region across photos. To achieve this, we build on tools from computer vision for image matching. Our experimental results on real photo collections demonstrate the feasibility and potential benefits of our approach.Natural Sciences and Engineering Research Council of Canada Postdoctoral FellowshipMassachusetts Institute of Technology.

4D Frequency Analysis of Computational Cameras for Depth of Field Extension
Full text linkDepth of field (DOF), the range of scene depths that appear sharp in a photograph, poses a fundamental tradeoff in photography---wide apertures are important to reduce imaging noise, but they also increase defocus blur. Recent advances in computational imaging modify the acquisition process to extend the DOF through deconvolution. Because deconvolution quality is a tight function of the frequency power spectrum of the defocus kernel, designs with high spectra are desirable. In this paper we study how to design effective extended-DOF systems, and show an upper bound on the maximal power spectrum that can be achieved. We analyze defocus kernels in the 4D light field space and show that in the frequency domain, only a low-dimensional 3D manifold contributes to focus. Thus, to maximize the defocus spectrum, imaging systems should concentrate their limited energy on this manifold. We review several computational imaging systems and show either that they spend energy outside the focal manifold or do not achieve a high spectrum over the DOF. Guided by this analysis we introduce the lattice-focal lens, which concentrates energy at the low-dimensional focal manifold and achieves a higher power spectrum than previous designs. We have built a prototype lattice-focal lens and present extended depth of field results
Exploring visual representation of sound in computer music software through programming and composition
No full textPresented through contextualisation of the portfolio works are developments of a practice in which the acts of programming and composition are intrinsically connected. This practice-based research (conducted 2009–2013) explores visual representation of sound in computer music software.
Towards greater understanding of composing with the software medium, initial questions are taken as stimulus to explore the subject through artistic practice and critical thinking. The project begins by asking: How might the ways in which sound is visually represented influence the choices that are made while those representations are being manipulated and organised as music? Which aspects of sound are represented visually, and how are those aspects shown?
Recognising sound as a psychophysical phenomenon, the physical and psychological aspects of aesthetic interest to my work are identified. Technological factors of mediating these aspects for the interactive visual-domain of software are considered, and a techno-aesthetic understanding developed.
Through compositional studies of different approaches to the problem of looking at sound in software, on screen, a number of conceptual themes emerge in this work: the idea of software as substance, both as a malleable material (such as in live coding), and in terms of outcome artefacts; the direct mapping between audio data and screen pixels; the use of colour that maintains awareness of its discrete (as opposed to continuous) basis; the need for integrated display of parameter controls with their target data; and the tildegraph concept that began as a conceptual model of a gramophone and which is a spatio-visual sound synthesis technique related to wave terrain synthesis. The spiroid-frequency-space representation is introduced, contextualised, and combined both with those themes and a bespoke geometrical drawing system (named thisis), to create a new modular computer music software environment named sdfsys

Kantian Aspects of Norman Bowie and R. Edward Freeman Business Ethics
No full textThe aim of the article is to present the Kantian aspects of N. Bowie and R.E. Freeman business ethics. Both authors are well-known in English-area business ethics as the thinkers working on stakeholder theory. R.E. Freeman, a founder of the stakeholder theory, stated the position called “Kantian capitalism” in 1988-1993. N. Bowie has been working on Kantian business ethics since 90‘s till now.
R.E. Freeman uses the second formulation of categorical imperative to redefine the aim of the corporation. According to him the traditional definition is false, because it treats stakeholders (excluding shareholders) as means to profi t (as a traditional firm’s aim). Thus, he defines the new aim as acting for interest of all stakeholders. However, this position is sensitive to strong objections what probably caused the author himself to reject it. Furthermore, Freeman’s position seems to be rather utilitarian than Kantian: acting for other’s interest as an aim of morally good company, weighing and sacrificing interest as a method of morally good acting.
N. Bowie’s application of Kantian ideas is wider and more systematic than Freeman’s approach. Nonetheless, it is also sensitive to many particular objections, especially misunderstanding of Kantian ideas. Bowie rejects the idea of purity of motive in Kantian ethics in order to justify the possibility of rational Kantian ethics application to area of business. Finally, making the possibility of application seems to be a proof for economical usefulness of Kantian ethics what makes this position close to utilitarianism too (like in Freeman case)
