光线照射镜面物体产生的镜面反射使得采集的图像产生高光现象,高光会影响很多视觉任务的精度。针对图片的去高光问题,在经典无监督学习CycleGAN的框架下提出了一种端到端的分层网络,该模型的输入为已标定的序列高光图像,输出为去除高光的图像。为了获取成对数据集以训练网络,使用可微分渲染器生成视角、光照可控镜面反射-漫反射成对合成数据集。无监督CycleGAN图像风格迁移网络作用于输入图像时,仅使用小批量的背景图片,即可将图像分解为前景与背景,图像风格迁移网络仅作用于前景,进一步提高了图像转换的精度。实验结果表明,该方法可有效去除高光。

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.
