Visual search errors are persistent in a laboratory analog of the incidental finding problem
Cognitive Research, 2020 When radiologists search for a specific target (e.g., lung cancer), they are also asked to report any other clinically significant “incidental findings” (e.g., pneumonia). These incidental findings are missed at an undesirably high rate.

The Act of Visual Attention [PDF]
Nature, 1962 THE act of visual attention consists of: a mental set directing a fixation of gaze, conjugate ocular movements, and accommodation of the lens and pupil. The mental set, particularly, is related to the general nervous and neuromuscular activity and to the autonomic function, as shown by the electrical resistance of the skin.

Visual Keyword Spotting with Attention [PDF]
Proceedings of the British Machine Vision Conference 2021, 2021 In this paper, we consider the task of spotting spoken keywords in silent video sequences -- also known as visual keyword spotting. To this end, we investigate Transformer-based models that ingest two streams, a visual encoding of the video and a phonetic encoding of the keyword, and output the temporal location of the keyword if present.

Eye Movements in Medical Image Perception: A Selective Review of Past, Present and Future
Vision, 2019 The eye movements of experts, reading medical images, have been studied for many years. Unlike topics such as face perception, medical image perception research needs to cope with substantial, qualitative changes in the stimuli under study due to ...

Pre-saccadic shifts of visual attention. [PDF]
PLoS ONE, 2012 The locations of visual objects to which we attend are initially mapped in a retinotopic frame of reference. Because each saccade results in a shift of images on the retina, however, the retinotopic mapping of spatial attention must be updated around the

Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence, 2022 While there has been substantial progress in learning suitable distance metrics, these techniques in general lack transparency and decision reasoning, i.e., explaining why the input set of images is similar or dissimilar. In this work, we solve this key problem by proposing the first method to generate generic visual similarity explanations with ...

Visual Navigation with Spatial Attention [PDF]
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021 This work focuses on object goal visual navigation, aiming at finding the location of an object from a given class, where in each step the agent is provided with an egocentric RGB image of the scene. We propose to learn the agent's policy using a reinforcement learning algorithm.

Presaccadic attention sharpens visual acuity
Scientific Reports, 2023 Visual perception is limited by spatial resolution, the ability to discriminate fine details. Spatial resolution not only declines with eccentricity but also differs for polar angle locations around the visual field, also known as ‘performance fields ...

Early vision and visual attention [PDF]
Psihologija, 2003 The question whether visual perception is spontaneous, sudden or is running through several phases, mediated by higher cognitive processes, was raised ever since the early work of Gestalt psychologists.

Visual attention and stability [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2011 In the present review, we address the relationship between attention and visual stability. Even though with each eye, head and body movement the retinal image changes dramatically, we perceive the world as stable and are able to perform visually guided actions. However, visual stability is not as complete as introspection would lead us to believe.
