Ask a smart home device for the weather forecast, and it takes several seconds for the device to respond. One reason this latency occurs is because connected devices don’t have enough memory or power ...
Artificial intelligence sheds light on how the brain processes language（图）
人工智能 大脑 处理语言 神经科学
2021/10/25
In the past few years, artificial intelligence models of language have become very good at certain tasks. Most notably, they excel at predicting the next word in a string of text; this technology help...
Wide Area Networks (WANs), the global backbones and workhorses of today’s internet that connect billions of computers over continents and oceans, are the foundation of modern online services. As Covid...
Two years have passed since the first workshop on Light Fields for Computer Vision at ECCV 2014, during which the field has advanced substantially. There have been breakthroughs in the differential th...
The Assumed Light Direction for Perceiving Shape from Shading
Shape-from-shading light-from-above shape perception, Lambertian shading
2016/5/24
Recovering 3D shape from shading is an ill-posed problem that the
visual system can solve only by making use of additional information
such as the position of the light source. Previous research has...
3D modeling of the Weary Herakles statue with a coded structured light system
Herakles cultural heritage structured light laser scanning digitization

基于动态Light Map的增强现实光照算法
增强现实 光照 动态更新
2009/11/17
为实现增强现实系统中光照的实时准确性，提出一种基于动态Light Map的快速光照算法。该方法通过采集视频图像中校准物体的像素亮度，计算出摄像机的信号放大量和信号偏置，并利用动态更新的Light Map所记录的环境光照信息实现虚、实场景之间的一致光照，且能够适应光照变化的场景。实验结果表明该算法的显示速度能够达到实时交互的帧率。
