Exploring Spatial Correlation for Visual Object Retrieval

Miaojing Shi, Xinghai Sun, Dacheng Tao, Chao Xu, George Baciu, Hong Liu
2015 ACM Transactions on Intelligent Systems and Technology  
BOVW does not consider the spatial correlation between visual words in natural images, and thus, biases the generated visual words towards noise when the corresponding visual features are not stable.  ...  Based on this co-occurrence matrix, we first present a novel high-order predictor to accelerate the generation of spatially correlated visual words, and a penalty tree (PTree) to continue generating the  ...  In this manner, (14) is approximated to Alg. 1 Exploring Spatial Correlation for Visual Object Retrieval Input: query image y, maximum number of searched nodes m Output: ranked list Image Representation  ...

Distinct Hippocampal versus Frontoparietal Network Contributions to Retrieval and Memory-guided Exploration

Donna J. Bridge, Neal J. Cohen, Joel L. Voss
2017 Journal of Cognitive Neuroscience  
Following retrieval of one object in a multi-object array, viewing was strategically directed away from the retrieved object toward nonretrieved objects, such that exploration was directed towards to-be-learned  ...  We examined eye movements during fMRI scanning to identify neural correlates of the influences of memory retrieval on exploration and learning.  ...  We thank Elise Gagnon and Bianca Marin for assistance with data collection and Peter Winter for helpful discussion.  ...

Eye Movements Actively Reinstate Spatiotemporal Mnemonic Content

Jordana S. Wynn, Kelly Shen, Jennifer D. Ryan
2019 Vision  
Eye movements support memory encoding by binding distinct elements of the visual world into coherent representations. However, the role of eye movements in memory retrieval is less clear.  ...  We review research linking gaze reinstatement to retrieval, describe the neural integration between the oculomotor and memory systems, and discuss implications for models of oculomotor control, memory,  ...  correlated significantly with memory for relative, but not absolute object locations.  ...

Vision and Touch: Multiple or Multisensory Representations of Objects?

Simon Lacey, Christine Campbell, K Sathian
2007 Perception  
We explore the relevance of visual imagery processes and highlight areas for further research, including the neglected question of asymmetric performance in the visuo^haptic cross-modal memory paradigm  ...  The relationship between visually and haptically derived representations of objects is an important question in multisensory processing and, increasingly, in mental representation.  ...  Visuo-spatial abilities of children are indeed correlated with cross-modal memory performance for both familiar (Johnson et al 1989) and unfamiliar objects (Stoltz-Loike and Bornstein 1987); and`good  ...

Active Navigation in Virtual Environments Benefits Spatial Memory in Older Adults

Melissa Meade, John Meade, Hélène Sauzeon, Myra Fernandes
2019 Brain Sciences  
We investigated age differences in memory for spatial routes that were either actively or passively encoded.  ...  Regression analyses showed that age and score on the Hooper Visual Organizational test predicted spatial memory accuracy, following the passive and active encoding of routes.  ...  For example, Sauzéon and colleagues [26] demonstrated that older adults had better memories for objects in a virtual apartment following active exploration rather than a passively guided tour.  ...

2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12

A Putative Model of Multisensory Object Representation

Simon Lacey, Noa Tal, Amir Amedi, K. Sathian
2009 Brain Topography  
We suggest that such access is modulated by object familiarity: spatial imagery may be more important for unfamiliar objects and involve IPS foci in facilitating somatosensory inputs to the LOC; by contrast  ...  Drawing on a recent distinction between object-and spatially-based visual imagery, we propose a putative model in which LOtv, a subregion of LOC, contains a modality-independent representation of geometric  ...  Thus, we suggest exploring 'object' and 'spatial' imagery as opposed to an undifferentiated 'visual' imagery approach.  ...
