Visual Brain and Visual Perception: How Does the Cortex Do Perceptual Grouping? [PDF]

, 1996
How the brain generates visual percepts is a central problem in neuroscience. We propose a detailed neural model of how LGN and the interblob cortical stream through V1 and V2 generate context-sensitive perceptual groupings from visual inputs.

A Label-Adaptive Smoothing Method With Multiscale Iterative Strategy for Ground-Satellite Image Geo-Localization

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Cross-view image geo-localization aims to estimate a camera's 3-DoF pose (location and orientation) by comparing the captured ground-level image to a geo-referenced overhead satellite image that covers the camera's local surroundings ...

Multimodal Perception and Machine Learning‐Empowered Human Machine Interfaces With Double‐Network Hydrogel Fibers

Advanced Functional Materials, EarlyView.
This work develops polyacrylamide‐alginate (PAM‐Alg) double‐network hydrogel fibers for multimodal perception and intelligent human‐machine interfaces. The covalent‐ionic network provides high strength, toughness, and stable conductivity. Easily woven into wearables and integrated with soft robots, the fibers enable object and temperature recognitions ...
