摘要:

我们提出了一个原则性的卷积神经金字塔(CNP)框架,用于一般的低级视觉和图像处理任务。它是基于基本的发现,许多应用程序需要大的结构理解的感受野。但是用于回归的相应神经网络要么堆叠许多层,要么应用大的内核来实现它,这在计算上是非常昂贵的。我们的金字塔结构可以大大扩大领域,而不牺牲计算效率。额外的好处包括自适应网络深度和渐进式上采样,可在VGA大小的输入上进行准实时测试。我们的方法利润广泛的应用,如深度/RGB图像复原,完成,噪声/伪影去除,边缘细化,图像滤波,图像增强和彩色化。

英文摘要:

We propose a principled convolutional neural pyramid (CNP) framework for general low-level vision and image processing tasks. It is based on the essential finding that many applications require large receptive fields for structure understanding. But corresponding neural networks for regression either stack many layers or apply large kernels to achieve it, which is computationally very costly. Our pyramid structure can greatly enlarge the field while not sacrificing computation efficiency. Extra benefit includes adaptive network depth and progressive upsampling for quasi-realtime testing on VGA-size input. Our method profits a broad set of applications, such as depth/RGB image restoration, completion, noise/artifact removal, edge refinement, image filtering, image enhancement and colorization.
