The Visual Perception of Elasticity
Two experiments were designed to evaluate human sensitivity to elasticity. Elastic objects bend when a force is applied to them. Observers saw two computer-generated bending rods (defined by the motions of 50 dots) on any given trial and were required to judge which rod was more flexible. …

Visual Perception of Biological Motion
… theoretical propositions for linking theories of visual perception and action. Two experiments were conducted to examine the roles played by relative and absolute motion components in the visual pick-up of information about activity identification and speed estimation. A human performer produced 7 …

Visual Perception in Hearing Sign Language Users
Deaf signers exhibit superior visual perception compared to hearing controls in several domains, including the perception of faces and peripheral motion. These visual enhancements are thought to compensate for an absence of auditory input. However, it is also possible that they reflect experience …

Visual perception of social groups in zebrafish
… In particular, I investigate how specific group visual features - such as number of elements, speed and overall amount of motion - might influence shoaling behaviour and be integrated within a dorsal thalamic circuit for the detection of social cues. I show that visual motion cues alone are …

Mini Cheetah Sensor Suite for Visual Perception
… does not have a method of collecting stabilized perception data. Research has been conducted at the University of Michigan, where a sensor suite for collecting perception data has been created. While the sensor suite is able to collect perception data, it is heavy and affects the agility of the …

Human visual perception under real-world illumination
How does the visual system achieve stable estimates of surface properties - such as reflectance and 3D shape - across changes in the illumination? Under arbitrary patterns of illumination this problem is ill-posed. However, in the real world, illumination is not arbitrary. Here I argue that the …

COMPOSITIONAL OBJECT-CENTRIC REPRESENTATIONS FOR ROBUST VISUAL PERCEPTION
… between modern vision models and the human visual cortex. While current models mimic hierarchical processing, they treat images as holistic inputs. In contrast, human vision learns objects as compositional building blocks, enabling robust recognition, occlusion reasoning, generalization, and …

The development of visual perception in deaf children
… auditory experience on development of visual perception. It was assumed that when auditory deprivation occurs at birth or at various ages at onset, there may be a corresponding delay in the development of certain visual perceptual processes. [TRUNCATED].

Neural mechanisms underlying core visual perception of objects
Visual perception of objects is a computationally challenging problem and fundamental to human well-being. Extensive previous research has revealed that the inferior temporal cortex (IT), a high-level visual area, is involved in various aspects of visual perception. Yet, little is known about: how …

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 …

Grounding robot motion in natural language and visual perception
<p>The current state of the art in military and first responder ground robots involves heavy physical and cognitive burdens on the human operator while taking little to no advantage of the potential autonomy of robotic technology. The robots currently in use are rugged remote-controlled vehicles. …

Certain aspects of visual perception in some "autistic" children
Identification strategies and patterns of visual inspection in relation to non-perceptual variables, rapport and discrimination set, were studied in 3 "autistic" Ss, using experimental materials relevant to various forms of visual perception. A qualitative, single case approach was followed, using …

Adapting deep neural networks as models of human visual perception
… (CNN) have been extremely successful for visual perception. In addition to performing well on the trained object recognition task, these CNNs also model brain data throughout the visual hierarchy better than previous models. However, these DNNs are still far from completely explaining …

Visual perception of moving objects: Effects of velocity and direction
… in velocity and direction of travel on the perception of a moving object. The effect of these changes on time-to-contact judgements was also investigated. Despite the extensive literature studying the perception of velocity, no substantive conclusions can be drawn as to the relationship …

Efficient Deep Learning Systems for Visual Perception on the Edge
Deep learning for visual perception on edge devices has become increasingly critical, driven by emerging applications in autonomous driving and AR/VR. Typically, sparse convolution on 3D point clouds and Visual Language Models (VLMs) for image processing are two important methods for visual …
