Perceptual grouping is usually defined by principles that associate distinct elements by virtue of image properties such as proximity, similarity, and occurrence within common regions. What role does learning play in forming a perceptual group? This study provides evidence that learning of shape associations leads to perceptual grouping. Participants were repeatedly exposed to pairs of unique s...

Remote sensing change detection (RSCD) is an important yet challenging task in Earth observation. The booming development of convolutional neural networks (CNNs) computer vision raises new possibilities for RSCD, and many recent RSCD methods have introduced CNNs to achieve promising improvements performance. In this paper we propose a novel multidirectional fusion perception network bi-temporal...
