Laplacian PCA and Its Applications
Dimensionality reduction plays a fundamental role in data processing, for which principal component analysis (PCA) is widely used. In this paper, we develop the Laplacian PCA (LPC...

Efficient Reduction of L-infinity Geometry Problems
This paper presents a new method for computing optimal L1 solutions for vision geometry problems, particularly for those problems of fixed-dimension and of large-scale. Our strat...

Trained Bilateral Filters and Applications to Coding Artifacts Reduction
Bilateral filtering is a simple and non-linear technique to remove the image noise while preserving edges. However, it is difficult to optimize a bilateral filter to obtain desire...

Distance Approximating Dimension Reduction of Riemannian Manifolds
We study the problem of projecting high-dimensional tensor data on an unspecified Riemannian manifold onto some lower dimensional subspace1 without much distorting the pairwise geo...
