A Convolutional Neural Network into graph space [article]

Indeed, convolution is a signal operation that are defined on euclidean spaces. This has restricted deep learning main use to euclidean-defined data such as sound or image.  ...  It shows robustness with respect to graph domain changes and improvement with respect to other euclidean and non-euclidean convolutional architectures.  ...  In order to minimize J , its gradient must be calculated with respect to W . This gradient will then be used to modify W itself. For calculus needs, let Conv be the output function of the Conv layer.  ...

Traditionally, the deformed shape is determined by the optimal transformation and weights for an energy term.  ...  3D shape editing is widely used in a range of applications such as movie production, computer games and computer aided design.  ...  For example, Yu et al. [34] propose a gradient domain mesh editing method which deforms meshes by interpolating gradient fields derived from user constraints.  ...

In this paper, we take the nonlocal principle beyond alpha estimation and extract overlapping image layers using the same Laplacian framework.  ...  Our matting technique, aptly called KNN matting, capitalizes on the nonlocal principle by using K nearest neighbors (KNN) in matching nonlocal neighborhoods, and contributes a simple and fast algorithm  ...  and more accurate solver than the one in [30] , which gives the optimal solution in closed form.  ...
