Conception en technologie CMOS d'un Système de Vision dédié à l'Imagerie Rapide et aux Traitements d'Images

2008

Our work presented in this thesis focuses on the design, testing and implementation of monolithics CMOS image smart sensors : The principle, performance and limitations. The hardware implementation of a vision smart system is the central link. HISIC is High Speed Image Capture with processing at pixel level. An experimental platform for instrumentation and evaluation of retina operators was conducted during this thesis. After a state of the smart sensors and CMOS retinas, the second part is dedicated to the study and design of the pixel image sensor HISIC. Two circuits were realized in CMOS technology. The first identied a new type of photo-detector, and the second, to create a prototype em…

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…

Fenomenologia e Cognitive Vision

2012

Vernon (2006) suggerisce di individuare un consenso in Cognitive Vision nella ricerca di capacità e attributi non-funzionali per un sistema robusto e adattivo. Questo contributo presenta una teoria informale di capacità percettive e motorie corrispondenti alle proprietà spaziali fenomeniche degli oggetti, vale a dire ai percetti la cui struttura è studiata in fenomenologia della percezione. Infine, se ne illustrano alcune implicazioni rispetto alle teorie cognitiviste e sensomotorie.

The Influence of the Lotus Flower Theme on the Perception Perception of Contemporary Urban Architecture

2021

We live in the visual culture times, when images continuously and daily are transferring some information. A visual message is also an indispensable element of architecture, in the semantic layer as an aesthetic value, sometimes fulfilling a narrative function by means of a symbol, which is an international visual code. Most of the symbols, hidden in painting, sculpture, or architecture, are elements of nature. The article discusses examples of architecture whose form is based on a lotus flower. Unification of urban landscapes leads to a decrease in the value of aesthetic impressions; therefore, the unique architecture builds the unique identity of the place.

The Concept of the Oceanic Feeling in Artistic Creativity and in the Analysis of Visual Artworks

2015

For several decades now, psychoanalytically oriented writers on art have used the concept of the oceanic feeling to designate feelings of oneness, limitlessness, and mania in artistic creativity and aesthetic experiencing. In this article, I examine critically the most influential account of the oceanic feeling in aesthetics, provided by art pedagogue and art critic Anton Ehrenzweig. Following his points of emphasis, I elaborate on the structural, perceptual, and affective aspects of oceanic states of mind. To illuminate further some of the central premises and problems of Ehrenzweig’s account, I assess two separate analyses of visual artworks that have incorporated his ideas. To conclude, …

Explicit behavioral detection of visual changes develops without their implicit neurophysiological detectability

2011

Change blindness is a failure of reporting major changes across consecutive images if separated, e.g., by a brief blank interval. Successful change detection across interrupts requires focal attention to the changes. However, findings of implicit detection of visual changes during change blindness have raised the question of whether the implicit mode is necessary for development of the explicit mode. To this end, we recorded the visual mismatch negativity (vMMN) of the event-related potentials (ERPs) of the brain, an index of implicit pre-attentive visual change detection, in adult humans performing an oddball-variant of change blindness flicker task. Images of 500 ms in duration were prese…

Performative Archives: The Visual Poetry of bpNichol and Derek Beaulieu

2019

International audience; La performance de l’archive dans la poésie visuelle de bpNichol et Derek Beaulieu”En s’adonnant à la dimension matérielle de l’écriture, la poésie visuelle s’engage dans une voie exploratrice qui pense ensemble matériau, écriture et mémoire. La figure de l’archive se decline au sens métaphorique pour dire cette relation. Elle traverse la tradition poétique en suivant la trace des formes adoptées par les divers supports de l’écrit. Si la poésie visuelle peut se dire archive de l’expérience scripturale, ses inscriptions sont le reflet du flux qui caractérise une esthétique et un environnement conditionnés de maniére croissante par des supports technologiques. Cet artic…
