Knowledge representation for robotic vision based on conceptual spaces and attentive mechanisms

1995

A new cognitive architecture for artificial vision is proposed. The architecture is aimed for an autonomous intelligent system, as several cognitive hypotheses have been postulated as guidelines for its design. The design is based on a conceptual representation level between the subsymbolic level processing the sensory data, and the linguistic level describing scenes by means of a high-level language. The architecture is also based on the active role of a focus of attention mechanism in the link between the conceptual and the linguistic level. The link between the conceptual level and the linguistic level is modelled as a time-delay attractor neural network.

Introduction: The World as a Stereogram

2014

This paper presents the historically most important theories of how visual perception is made spatial in the cognitive processing of the sensory input to the eye. All of them involve active engagement of the mind. Firstly, in the medieval theories physiological processes developed three-dimensional imagery in the brain, and active mental processing was needed to build coherence in the perceptual experience as a whole but not to yield the basic idea of spatiality. Secondly, according to Descartes, the eyes produced a unified two-dimensional visual image that was neurally transmitted to the inner surface of the brain. The innate conception of three-dimensional spatiality was superimposed inte…

Towards a conceptual representation of actions

2000

An autonomous robot involved in missions should be able to generate, update and process its own actions. It is not plausible that the meaning of the actionsus ed by the robot isgiv en form the outside of the system itself. Rather, this meaning should be anchored to the world through the perceptual abilitiesof the robot. We present an approach to conceptual action representation based on a "conceptual" level that actsasan intermediate level between symbolsand data coming form sensors. Symbolic representations are interpreted by mapping them on the conceptual level through a mapping mechanism based on artificial neural networks.

Transcendental Apperception: Consciousness or Self-Consciousness? Comments on Chapter 9 of Patricia Kitcher'sKant's Thinker

2014

AbstractA core thesis of Kitcher's is that thinking about objects requires awareness of necessary connections between one's object-directed representations ‘as such’ and that this is what Kant means by the transcendental unity of apperception. I argue that Kant's main point is the spontaneity or ‘self-made-ness’ of combination rather than the requirement of reflexive awareness of combination, that Kitcher provides no plausible account of how recognition of representations ‘as such’ should be constituted and that in fact Kant himself appears to lack the theoretical resources to clearly distinguish between (first-level) consciousness and self-consciousness or apperception properly so-called.

Geometry/Time Measurement/Sundials Graphical Resolution via Algorithmic and Parametric Processes

2018

Every people, in every historical period, developed methods to measure Time both at a daily scale and at a yearly scale. Some of them constructed sundials to represent the apparent trajectory of the Sun around the Earth, by using and developing tools from descriptive and projective Geometry, mainly. This subject acquired a great multidisciplinary interest since ancient times, also for Science of Representation applications. This study presents the first results of an ongoing research concerning some aspects related to Time Measurement. The geometric-spatial setting of the Sun-Earth system is described and is structured parametrically via algorithms, following the known conventions shared an…

Color and Flow Based Superpixels for 3D Geometry Respecting Meshing

2014

We present an adaptive weight based superpixel segmentation method for the goal of creating mesh representation that respects the 3D scene structure. We propose a new fusion framework which employs both dense optical flow and color images to compute the probability of boundaries. The main contribution of this work is that we introduce a new color and optical flow pixel-wise weighting model that takes into account the non-linear error distribution of the depth estimation from optical flow. Experiments show that our method is better than the other state-of-art methods in terms of smaller error in the final produced mesh.

Architectural Representation: a Tool for Urban Regeneration : the Colour Plan of Egadi Islands

2018

The Egadi Islands, at the western end of Sicily, preserve a peculiar architectural and environmental heritage. The work of people – related to tuna fishing, stone extraction and agriculture – has created, over time, an exceptional landscape. The nature, colour and texture of the local stone have given shape to a traditional architecture that, today, risks to disappear and to be replaced by new anonymous buildings. Furthermore, the pressure of tourism threatens to damage this delicate balance established, over centuries, between people and environment. Therefore, the Local Administration decided to adopt a Colour Plan to manage the inevitable processes of territorial transformations. The Arc…

A counterexample to Feit's Problem VIII on decomposition numbers

2016

We find a counterexample to Feit's Problem VIII on the bound of decomposition numbers. This also answers a question raised by T. Holm and W. Willems.
