Deconstruction of compound objects from image sets

We propose a method to recover the structure of a compound object from multiple silhouettes. Structure is expressed as a collection of 3D primitives chosen from a pre-defined library, each with an associated pose. This has several advantages over a volume or mesh representation both for estimation and the utility of the recovered model. The main challenge in recovering such a model is the combinatorial number of possible arrangements of parts. We address this issue by exploiting the sparse nature of the problem, and show that our method scales to objects constructed from large libraries of parts

Negative Object; Apophatic Gesture

Representing absence without naming or referencing the objects in question brings to mind the example of apophaticism – a tradition in theology that names what the divine is not, exploring the limits of human knowledge through negation. Considering the absent object in an apophatic way can foster attentiveness to the things that populate our lives, revealing that when objects go missing or lose their usefulness there is an indefinite loss - not only of the object itself, but also of worlds and relationships that once existed. It might seem a lofty term for lowly objects – a fur coat, a postcard, a bulldog clip - but it is a vernacular sense of the apophatic I wish to access

Videocentric criticism, postmodernism and the deconstruction of television

This research offers an alternative method to the study of visual narrative. It criticizes Western society\u27s videocentrism, or centering of television as the predominant medium of communicating to mass society. This method is known as videocentric criticism; Chapter one assesses the modern and postmodern condition. Philosophy from the Greek and modern Enlightenments suggests that Western society\u27s videocentrism is a developing process originating in these periods. It then addresses modernity and postmodernity. Postmodern cultural phenomena that progressed in proximity with the evolution of television is discussed; Chapter two defines videocentric criticism. Narrative, structuralism, post-structuralism, and deconstruction are applied to televisual information. An example of televisual information is partially deconstructed; Chapter three proposes the Levels of Televisual Reality, which are similar to Plato\u27s Divided Line Analogy. The Levels of Televisual Reality suggest a person interacts with televisual information as an artificial form of: environment, experience, and consciousness. Examples are used

“Let's Make a List”: James Schuyler's taxonomic autobiography

August 21, 1970 A few sound[s] are embedded in the fog – a gull mewing, different far off fog horns – like unset polished stones laid out in cotton wool. Tuesday, March 5, 1985 At six AM the heavy gray burns a heavier blue. Rain, water drops clinging to the balcony. There is an ethical consideration in James Schuyler's Diary. While we have spent the last fifty years grappling with the aesthetic problems of how to represent the unrepresentable, how to present the unpresentable, and how to signify the significant, little time has been spent considering the status of representations of the unremarkable. There is a whole history in American poetry and literature of validating the everyday, making it special, but Schuyler never really does that. Are things special just because we say so, or rather because we note them down? Do we name things into being, at least linguistic or literary being? The Diary asks these questions and in doing so it broaches the kind of postmodern ethical questions that one finds in the recent work of Lyotard, Derrida, and Nancy. These questions are significant not in the normal sense of the reasons for such interrogations or the answers expected, but rather because they represent a desire on the part of Schuyler to ask after otherness, to try to elicit a response from the other while respecting that such a response may not be comprehensible even if it is forthcoming. I would like here to posit a desire to ask after the other first before one asks after oneself, to enquire without any hope of a satisfactory answer as such as the postmodern ethical position, and to suggest that the autobiographical slant of Schuyler's work is, paradoxically considering the nature of autobiography, just such a positioning of his self in relation to the world

Existential Communication and Leadership

The aim of this article is to introduce and explain a number of important existentialist philosophers and concepts that we believe can contribute to a critical approach to leadership theory. Emphasis is placed on understanding the nature of communication from an existentialist perspective and so Jaspers' conceptualization of existential communication is introduced along with important related concepts that may be regarded as important facets of leader communication including Being-in-the-world, the Other, intersubjectivity, dialogue and indirect communication. Particular attention is paid to Buber's ideas on communication as relationship and dialogue. Throughout, reference is made to contemporary, and what is often regarded as orthodox, thinking regarding the centrality of communication to leadership practice as a means by which to highlight the salience of an existentialist analysis

Lacan’s Construction and Deconstruction of the Double-Mirror Device

In the 1950s Jacques Lacan developed a set-up with a concave mirror and a plane mirror, based on which he described the nature of human identification. He also formulated ideas on how psychoanalysis, qua clinical practice, responds to identification. In this paper Lacan’s schema of the two mirrors is described in detail and the theoretical line of reasoning he aimed to articulate with aid of this spatial model is discussed. It is argued that Lacan developed his double-mirror device to clarify the relationship between the drive, the ego, the ideal ego, the ego-ideal, the other, and the Other. This model helped Lacan describe the dynamics of identification and explain how psychoanalytic treatment works. He argued that by working with free association, psychoanalysis aims to articulate unconscious desire, and bypass the tendency of the ego for misrecognition. The reasons why Lacan stressed the limits of his double-mirror model and no longer considered it useful from the early 1960s onward are examined. It is argued that his concept of the gaze, which he qualifies as a so-called “object a,” prompted Lacan move away from his double-mirror set-up. In those years Lacan gradually began to study the tension between drive and signifier. The schema of the two mirrors, by contrast, focused on the tension between image and signifier, and missed the point Lacan aimed to address in this new era of his work

Bioimage Data Analysis Workflows ‒ Advanced Components and Methods

This open access textbook aims at providing detailed explanations on how to design and construct image analysis workflows to successfully conduct bioimage analysis. Addressing the main challenges in image data analysis, where acquisition by powerful imaging devices results in very large amounts of collected image data, the book discusses techniques relying on batch and GPU programming, as well as on powerful deep learning-based algorithms. In addition, downstream data processing techniques are introduced, such as Python libraries for data organization, plotting, and visualizations. Finally, by studying the way individual unique ideas are implemented in the workflows, readers are carefully guided through how the parameters driving biological systems are revealed by analyzing image data. These studies include segmentation of plant tissue epidermis, analysis of the spatial pattern of the eye development in fruit flies, and the analysis of collective cell migration dynamics. The presented content extends the Bioimage Data Analysis Workflows textbook (Miura, Sladoje, 2020), published in this same series, with new contributions and advanced material, while preserving the well-appreciated pedagogical approach adopted and promoted during the training schools for bioimage analysis organized within NEUBIAS – the Network of European Bioimage Analysts. This textbook is intended for advanced students in various fields of the life sciences and biomedicine, as well as staff scientists and faculty members who conduct regular quantitative analyses of microscopy images
