Seasonal-Aware Scale-Semantic Consistency Alignment Change Detection Network [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Change detection in remote sensing imagery is a crucial method for obtaining dynamic information about land cover. However, pseudo-changes caused by seasonal variations pose a significant challenge to detection accuracy.

Object-centred spatial reference in 4-month-old infants [PDF]

, 2005
An appreciation of object-centred spatial relations involves representing a 'within-object' spatial relation across changes in the object orientation. This representational ability is important in adult object recognition [Biederman, I.

Spatial Heterogeneity in Bistable Figure-Ground Perception.

, 2021
The appearance of visual objects varies substantially across the visual field. Could such spatial heterogeneity be due to undersampling of the visual field by neurons selective for stimulus categories?

Hyperspectral Anomaly Detection Using Dual-Branch Network Based on Frequency Domain Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Existing deep learning-based hyperspectral anomaly detection methods often overlook frequency domain features, hindering the ability to effectively distinguish between background and anomalies.

A semantic and language-based representation of an environmental scene [PDF]

, 2010
The modeling of a landscape environment is a cognitive activity that requires appropriate spatial representations. The research presented in this paper introduces a structural and semantic categorization of a landscape view based on panoramic photographs

Urban biodiversity by design: A multi-taxa, causal evaluation of targeted habitat interventions and ecological ecosystem across major Chinese cities

Ecological Indicators
Rapid urbanization in China fragments habitats and simplifies green space structure, but cities are increasingly piloting compact “ecological micro-interventions” whose cross-taxa benefits remain weakly quantified.

Categorical perception of animal patterns [PDF]

, 2010
As part of the more general issue of whether culture can affect perception, the present paper addresses the Whorfian question of whether the language available to describe perceptual experience can influence the experience itself.

Eye movements during visual imagery and perception show spatial correspondence but have unique temporal signatures

, 2021
Eye fixation patterns during mental imagery are similar to those during perception of the same picture, suggesting that oculomotor mechanisms play a role in mental imagery (i.e., the “looking at nothing” effect).

Impact of spatial scale on the sensitivity of the water supply-demand balance to driving factors

Ecological Indicators
Escalating water insecurity in the Yellow River Basin (northern/northwestern China) reflects a deepening structural disconnect between climate-driven water yield (WY) — shaped by steep precipitation gradients from the Tibetan Plateau across the Loess ...
