高质量的镜头通常价格昂贵,但它贵也有贵的理由,这些镜头使用大量特别设计的元素去消除畸变和扭曲。但如果你也能做到,甚至能自动完成?加拿大不列颠哥伦比亚研究人员正在开发一种软件替代,可以让劣质廉价镜头拍出完美高质量照片。他们的技术已经在今年早些时候举行的SIGGRAPH 2013大会上公开演示,简单来说,就是软件估算出不同对象不同距离的点分散函数,修正模糊、失真和像差,重建恢复到高质量的图像。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
