Perceiving the similarity between images has been a long-standing and fundamental problem underlying various visual generation tasks. Predominant approaches measure the inter-image distance by computing pointwise absolute deviations, which tends to estimate the median of instance distributions and leads to blurs and artifacts in the generated images. This paper presents MoNCE, a versatile metric that introduces image contrast to learn a calibrated metric for the perception of multifaceted inter-image distances. Unlike vanilla contrast which indiscriminately pushes negative samples from the anchor regardless of their similarity, we propose to re-weight the pushing force of negative samples adaptively according to their similarity to the anchor, which facilitates the contrastive learning from informative negative samples. Since multiple patch-level contrastive objectives are involved in image distance measurement, we introduce optimal transport in MoNCE to modulate the pushing force of negative samples collaboratively across multiple contrastive objectives. Extensive experiments over multiple image translation tasks show that the proposed MoNCE outperforms various prevailing metrics substantially.

我们开发了一个有效的点云渲染管道,用于新的视图合成,它可以实现高保真的局部细节重建,实时渲染和用户友好的编辑。在我们的管道的心脏是一个自适应频率调制模块,称为自适应频率网络(AFNet),它利用超网络来学习局部纹理频率编码,该编码连续注入自适应频率激活层以调制隐式辐射信号。该机制以较小的计算量提高了网络的频率表达能力,具有更丰富的频率基支持。为了进一步提高性能,还提出了一个预处理模块,通过点不透明度估计点云几何优化。与隐式渲染相比,我们的管道支持基于点云操作的高保真交互式编辑。在NeRF-Synthetic,ScanNet,DTU和Tanks and Temples数据集上的大量实验结果表明,与最先进的方法相比,我们的方法在PSNR,SSIM和LPIPS方面取得了优异的性能。
