In this article, we apply sparse constraints to improve optical flow and trajectories. We apply sparsity in two ways. First, with two-frame optical flow, we enforce a sparse representation of flow patches using a learned overcomplete dictionary. Second, we apply a low-rank constraint to trajectories via robust coupling. Optical flow is an ill-posed underconstrained inverse problem. Many recent approaches...
Cloud computing can be defined as the use of new or existing computing hardware and virtualization technologies to form a shared infrastructure that enables web-based value added services. The three predominant service models are infrastructure, platform, and software-asa-service. Infrastructure-as-a-Service (IaaS) can be defined as the use of servers, storage, and virtualization to enable utility...
