如果已知噪声服从的高斯分布,那么对于根据这个分布+clean image合成的noisy image,可以直接得出其ground-truth的noise level or noise level map。 不太确定的事情: 另外读到这里你肯定发现了论文中的noise level和本文中的noisePower不是一个东西,网上没有找到两者特别明显的概念区别,所以noise level可能是作者对σ起...

Other tools such as NoiseMap with its advanced acoustic model and NMAP with the NOISEFILE database and noise-power-distance data can simulate noise from various AAM vehicle configurations. To measure noise and have noise certification, Senzig et al.used tests like sound exposure level (SEL) to...
The first column displays the training and validation loss curves under the condition that the accurate noise map was used during the training process. For the second column, the noise maps were averaged and the conventional SURE approach using a scalar noise level was employed. For the third ...
Given a paired signal training dataset{(x^,x)1,…,(x^,x)N}, wherex^represented the noisy version of the clean fetal ECG signalxfor a given sample, our goal is to learn the right parameter values of a neural network so that the network can map the noisy signalx^to the clean signal...
摘要: The following gives an overview of how sound level measurements can be used in noise mapping and how GPS can help in determining measurement position. There are two types of noise maps using input of measured noise levels: Short- or long-term measurement-based, where 被引量: 2 年份...
In this study, inspired by the previous work of Noise2Noise training, we hypothesize that instead of training the network to map noisy samples to high quality targets, we could train a similar neural network by pairing one noise realization to an ensemble of noise realizations. We compared a ...
Est-Net is to estimate the noise level map which plays the role of guidance. De-Net is for image denoising. The SCAB combines the spatial attention mechanism and channel attention mechanism. The spatial mechanism can reweight the feature maps based on the position of different feature maps ...
Scaling regularities are examined associated with effect of additive noise on a critical circle map at the golden-mean rotation number. We present an improved numerical estimate for the scaling constant of Hamm and Graham (Phys. Rev. A46, (1992) 6323) responsible for the effect of noise, γ...
A noise map of the city of Valdivia is created as a way to evaluate the noise of the city. This is a process that is usually associated with high operative costs. Some statistical techniques have been employed that have allowed the extrapolation of some measured values to assess noise at di...
