Differential Effects of Divided Attention on Object Representations
… theories have been developed in explanation of object perception, such as Feature Integration Theory, which posits that an object is perceived after two stages: a pre-attentive stage and a focused attention stage. It is during the focused attention stage that a representation of the perceived …

Hierarchical volumetric object representations for digital fabrication workflows
… In addition, tools are based on boundary representations, which are fragile and can easily describe nonsensical objects. This thesis addresses these issues with a set of tools for end-to-end digital fabrication based on volumetric solid models. Workflows are modular, making it easy to add …

Extraction of 3D Object Representations from a Single Range Image
… construction of a computer model of 3D solid objects from a single range image. This research has many real world applications, including robotic environments and the inspection of industry parts. The most common methods for 3D-object extraction are based on stereo reconstruction and …

Towards Self-Supervised Object Representations and 3D Scene Graph Based Navigation
3D Scene Graphs are powerful hierarchical representations of environments that combine spatial and semantic information into multiple levels of abstraction. 3D Scene Graphs are useful for a wide range of planning tasks in robotics that benefit from high-level semantic knowledge, and also capture …

Action-related organization of object representations in human visual cortex and topographic models
Decades of research have shown that object representations in occipitotemporal cortex (OTC) are organized by multiple spatial and functional principles, including category-selective areas and large-scale topographic maps structured by properties such as animacy and real-world size. In parallel, …

Factor structure of the assessment of qualitative and structural dimensions of object representations (AOR) scale
… interactions with parents form parental representations (PR) that have been empirically associated with psychopathology. The Assessment of Qualitative and Structural Dimensions of Object Representations scale (AOR; Blatt et al., 1992) is one measure of PR that benefits from measuring …

Cognitive-developmental learning for a humanoid robot : a caregiver's gift
… are then applied to developmentally acquire new object representations. The humanoid robot therefore sees the world through the caregiver's eyes. Building an artificial humanoid robot's brain, even at an infant's cognitive level, has been a long quest which still lies only in the realm of our …

A functional model of similarity
… are then analysed in terms of their implicit object representations and cognitive processes. The distinction between the'class inclusion' and 'distance relation' models of similarity is shown tobe qualitative in nature, and to correspond to the analytic-synthetic distinction in terms of …

Systemic software reuse through analogical reasoning
… a methodology based upon an extension of object-oriented design principles that promotes decoupling of object representations and provides mechanisms for composing systems from abstract objects, relations, and frameworks; techniques for measuring the degree that two systems are …

The Effect of Aging on Object Representation
… older adults (OA) representation of real-world objects through different cognitive paradigms probing visual working memory (vWM) and attention. OAs are known to demonstrate difficulties in these two cognitive domains, however, an under-researched in the aging field is the possible influence of …

The Effect of Active Learning on Viewpoint Dependence for Novel Objects
Active learning of novel objects can facilitate subsequent object recognition and discrimination, but the reasons for its beneficial effects remain unclear. One potential explanation is that active learning enables the formation of a more detailed, realistic, or useful neural object representation …

Synthesis and perception of sounds from physical interactions reveals auditory intuitive physics
Object interactions – collisions, scraping and rolling – create many of the sounds that we hear in the world around us. These sounds are generated via lawful physical dynamics. Anecdotally, humans possess some intuitive knowledge of the physical generative processes underlying sound production, but …

Pattern Separation in the Ventral Visual Stream
… transformation from feature-based visual representations to conjunctive whole-object representations, with the latter allowing for distinct coding even when objects have significant feature overlap. In the current study, we asked whether this transformation can be understood as pattern …

Generation of qualitative spatio-temporal representations from visual input
The simultaneous interpretation of object behaviour from real world image sequences is a highly desirable goal in machine vision. Although this is rather a sophisticated task, one method for reducing the complexity in stylized domains is to provide a context specific spatial model of that domain. …

The Perceptual Specificity of Representations of Complex Scenes for Rotation, Translation, and Reflection
… investigated the perceptual specificity of scene representations for various kinds of changes to naturalistic scenes using eye movements and a direct measure of memory (familiarity or recognition). In Experiment 1, both measures indicated that scene representations, like object representations, …

It's a kind of magic: exploring the role of the living in effecting food and drink offerings in private mortuary cults of late Old Kingdom Egypt
… supply was provided via image, text, and object representations of sustenance in the tomb. This study examines these ‘modes’ through which offerings were present and presented. Complementary theoretical frameworks are employed in case studies that analyse illustrative examples of the …

Principles governing the large-scale organization of object selectivity in ventral visual cortex
… functions. An example of such a region is the objectselective ventral visual cortex (VVC) in humans. This region, which is involved in the high-level task of object recognition, is comprised of several functionally defined, category-selective subregions that are laid out with remarkable …

Masked antipriming: a behavioral and event-related potential examination of short-term antipriming effects
… stimuli measured as impaired identification of objects following recent encoding of other objects (e.g.,identifying a piano is impaired by having recently viewed objects that are not pianos; Marsolek et al., 2006). Antipriming effects have been established in several behavioral experiments (with …

Saccadic decision-making in dynamic real-world scenes
… study, we systematically explored the role of object-based attention in saccadic decision-making. We introduced our computational framework that simulates the saccadic decision-making process and reproduces the temporal and spatial aspects of human gaze behavior. Its modular and mechanistic …

Long-term Object-based SLAM in Low-dynamic Environments
