Images reconstructed from brain activity

Witryna7 mar 2024 · 自从电子医疗系统通过分享数据协助医生进行远程诊断以来，数据安全一直是研究和讨论的重要主题(Li等，2013)。病历和医学图像中的患者信息是黑客极为关注的内容，而患者的医疗数据在医院内部网或互联网传输过程中，往往缺乏有效保障其保密性、完整性和隐私性的安全工具，可能会遭遇一些 ... WitrynaAbstract. Understanding how the brain encodes external stimuli and how these stimuli can be decoded from the measured brain activities are long-standing and challenging questions in neuroscience. In this paper, we focus on reconstructing the complex image stimuli from fMRI (functional magnetic resonance imaging) signals.

Attentionally modulated subjective images reconstructed from brain activity

WitrynaQuantitative and qualitative evaluations were conducted with test images. The results showed that the reconstructed image achieved comparable, accurate reproduction of the presented image in both high-level semantic category information and low-level pixel information. The framework we propose shows promise for decoding the brain activity.
