全变分在图像处理中最直接和最有效的应用为图像去噪和复原。Rudin等人(Rudin1990)观察到,受噪声污染的图像的总变分比无噪图像的总变分明显的大。总变分定义为梯度幅值的积分。限制总变分就会限制噪声。 用在图像上,total variation loss可以使图像变得平滑。信号处理中,总变差去噪,也称为总变差正则化,是最常用于数字...
total variation, produced by the ConvNet. This can be seen as a regularization term that promotes piecewise smoothness of the label probability vector image produced by the ConvNet during learning. The unsupervised loss function is combined with a supervised loss in a semi-supervised setting to ...

Loss functions are an essential part in modern data-driven approaches, such as bi-level training scheme and machine learnings. In this paper, we propose a loss function consisting of ar-order (an)-isotropic total variation semi-normsTVr,r∈+, defined via the Riemann–Liouville (RL) ...

The proposed models can have effective and automatic control over geometric features of the inpainted images including sharp edges, even in the presence of substantial loss of wavelet coefficients, including in the low frequencies. Existence and uniqueness of the optimal inpaintings are also carefully ...

Second, it leads to a contrast loss near edges that mainly depends on its curvature. Thus, especially corners in objects, but also regions with strongly varying curvature are resolved badly. In order to combine the benefits of anisotropic filtering and total variation regularization, we ...
Since 53BP1 KO fully rescued PARPi sensitivity in Brca1Δ11/Δ11 and Brca1Δ2/Δ2 cells but not in Brca1ΔC/ΔC cells [13,14,15,16], we examined if 53BP1 KO could rescue the PARPi sensitivity caused by complete BRCA1 loss. As Brca1−/− MEFs could not be obtained for ...
