This limits the use of seismic data for subsequent imaging or inversion applications. Recently, dictionary learning has gained remarkable success in seismic data denoising and interpolation. Variants of the patch-based learning technique, such as the K-singular value decomposition (K-SVD) algorithm, have been shown to improve denoising and interpolation performance compared with the analytic transform-based methods. However, patch-based learning algorithms work on overlapping patches of data and do not take the full data into account during reconstruction. In contrast, the data patches (convolutional sparse coding [CSC]) model treats signals globally and, therefore, has shown superior performance over patch-based methods in several image processing applications. As a consequence, we test use of the CSC model for seismic data denoising and interpolation. In particular, we use the local block coo...

In this paper, we introduce a simple yet efficient hand-object reconstruction algorithm. To this end, we exploit the fact that both the poses and the meshes are graphs-based representations of the hand-object with different levels of details. This allows taking advantage of the powerful Graph Convolution networks (GCNs) to build a coarse-to-fine Graph-based hand-object reconstruction algorithm. Thus, we start by estimating a coarse graph that represents the 2D hand-object poses. Then, more details (e.g. third dimension and mesh vertices) are gradually added to the graph until it represents the dense 3D hand-object meshes. This paper also explores the problem of representing the RGBD input in different modalities (e.g. voxelized RGBD). Hence, we adopted a multi-modal representation of the input by combining 3D representation (i.e. voxelized RGBD) and 2D representation (i.e. RGB only). We include intensive experimental evaluations that measure the ability of our simple algorithm to achieve state-of-theart accuracy on the most challenging datasets (i.e. HO-3D and FPHAB). INDEX TERMS Hand pose estimation, hand shape estimation, hand-object interaction, graph convolution, machine learning.
