Resilient Object Perception for Robotics
… to perceive and understand the geometry of objects in the environment. Object perception needs to reliably work in a variety of scenarios and preserve a desired level of performance in the face of outliers and shifts from the training domain. Obtaining such a level of performance requires …

Evolving Video Analysis: From Object Perception to Holistic Understanding
… significant challenges remain in both video object perception and holistic video understanding, which are crucial for applications ranging from autonomous driving to interactive media. This thesis aims to address these challenges by developing innovative methodologies that enhance the …

Object perception for students with visual impairments: A virtual reality approach
… (VI). It examined how VR could improve object perception and detail identification, increasing accessibility and addressing limitations of traditional visual-centric teaching methods. Procedure: A quantitative approach with anecdotal notation assessed VR’s impact on object perception. …

Beyond Conscious Object Perception: Processing and Inhibition of the Groundside of a Figure
Object perception is necessary to our understanding of the visual world, yet its neural mechanism remains poorly understood. The goal of this dissertation is to shed light on this mechanism. Current computational models of object perception suggest that regions on opposite sides of a shared border …

Visual perception and representation of objects and faces
Interpreting the results of visual object perception experiments is too often ill-posed due to the disparate and sparse choice of stimuli. To address this problem, we have developed a flexible new technique called Random Image Structure Evolution (RISE). In the simplest case, RISE involves the …

Visual Enumeration: Subitizing and Its Nature
… These findings suggest subitizing as part of the object perception processes. A surprising difference between two display-change conditions in which one item was either inserted in or removed from the display during a saccade to the stimulus pattern further suggests that subitizing is explained …

Learning about dynamic objects and recognizing static form
The effects of observed object motion on object perception are examined in two sets of studies. The first section of the thesis provides a thorough examination of various untested aspects of the basic "temporal association" hypothesis, which suggests that object motion provides a principled basis …

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 …

Inferring Shape and Material from Sound
Humans infer rich knowledge of objects from both auditory and visual cues. Building a machine of such competency, however, is very challenging. One possible solution is to rely on supervised learning, which requires a large-scale dataset containing sounds of various objects, with clean labels on …

Cortical Processing of Visual Parts and Wholes
Visual perception theory distinguishes between two distinct levels of object processing: holistic, based on global shape, and configural, based on local features and/or component parts. Empirical evidence suggests that different cortical regions may support these levels; holistic processing …

Electrophysiological correlates of multiple object processing
… street depend on our ability to process multiple objects simultaneously. According to some theories this ability relies on at least two stages or mechanisms related respectively to visual attention and visual working memory (WM). The early stage of multiple object processing – individuation – is a …

The Neural Development of Visuohaptic Object Processing
Object recognition is ubiquitous and essential for interacting with, as well as learning about, the surrounding multisensory environment. The inputs from multiple sensory modalities converge quickly and efficiently to guide this interaction. Vision and haptics are two modalities in particular that …

Understanding cognitive differences in processing competing visualizations of complex systems
… - geon diagrams based on structural object perception theory and UML diagrams based on object modeling - are investigated to understand the cognitive processes that underlie reasoning with different types of visualizations. Specifically, the two visualizations are used to represent …

Enhancement of the Fynbos Leaf Optical Recognition Application (FLORA-E)
Object perception, classification and similarity discernment are relatively effortless tasks in humans. The exact method by which the brain achieves these is not yet fully understood. Identification, classification and similarity inference are currently nontrivial tasks for machine learning enabled …

Neurotrophic Theory of Accelerated Temporal Cortex Maturation in the Valproic Acid Rat Model of Autism
… temporal lobe play a critical role in mediating object perception, long term semantic memory and social communication. A unique feature of this region is its delayed acquisition of peak cortical thickness, which is not reached until the second decade of life. In the majority of individuals with …

Aesthetics of Diagrammatic Contemplation: Abhinavagupta's and Martin Heidegger's Views on Being as Such and How It Can Be Disclosed Through Aesthetic Contemplation
… disclosed by surpassing the duality of subject/object perception through aesthetic contemplation. Heidegger's post-aesthetic approach aims to overcome the subject-object duality to uncover two hidden onto-epistemological dimensions: the mode of practical engagement and Being as such, also …
