Spectral methods refer to the problem of finding eigenvectors of an affinity matrix. Despite promising performance on revealing manifold structure, they are limited in its applicability to large-scale problems due to the high computational cost of eigendecomposition. Nyström method, as a classic method, seeks an approximate solution by first solving a smaller eigenproblem defined on a subset of landmarks,...
2D articulated human pose tracking in monocular image sequences remains an extremely challenging task due to background cluttering, variation in body appearance, occlusion and imaging conditions. Most of the current approaches only deal with simple appearance and or connected body part dependencies, especially the tree- structured priors assumed over body part connections. Such prior excludes...
We work on the task of 2D articulated human pose tracking in monocular image sequences, an extremely challenging task due to background cluttering, variation in body appearance, occlusion and imaging conditions. Most of current approaches only deal with simple appearance and body part dependencies, especially the Gaussian tree-structured priors assumed over body part connections. Such prior...
This paper presents a robust and fully-automatic human motion tracking system without motion priors information using a camera in a fixed location. Bottom-up estimation approaches have recently been applied to such tasks with some success. However, the performance of these approaches is limited by the difficulty of building an effective appearance model. In particular, the appearance model must be...
Fuzzy C-Means(FCM) algorithm is one of the most popular methods for image segmentation, but it is in essence a technology of searching local optimal solution. The algorithm's initial clustering centers are the stochastic selection which causes it to depend on the selection of the initial cluster centers excessively. It always converges at the local optimum and is sensitive to noise. In order to overcome...
Transit Metropolis is a model of urban currency in terms of energy conservation and highly active. Moreover, to realize this imagine must rely on choosing the public traffic trip intelligently at first. In Guangzhou, there are many reasons to affect the public traffic trip; thereinto, the uppermost are traffic congestion, inconvenient transfer, and high tripping fare. Therefore, the paper replan and...
