Actions as space-time shapes

TL;DR: The method is fast, does not require video alignment and is applicable in many scenarios where the background is known, and the robustness of the method is demonstrated to partial occlusions, non-rigid deformations, significant changes in scale and viewpoint, high irregularities in the performance of an action and low quality video.

Lambertian reflectance and linear subspaces

TL;DR: It is proved that the set of all Lambertian reflectance functions (the mapping from surface normals to intensities) obtained with arbitrary distant light sources lies close to a 9D linear subspace, implying that, in general, theSet of images of a convex Lambertian object obtained under a wide variety of lighting conditions can be approximated accurately by a low-dimensional linear sub space, explaining prior empirical results.

Lambertian reflectance and linear subspaces

TL;DR: It is proved that the set of all reflectance functions (the mapping from surface normals to intensities) produced by Lambertian objects under distant, isotropic lighting lies close to a 9D linear subspace, implying that the images of a convex Lambertian object obtained under a wide variety of lighting conditions can be approximated accurately with a low-dimensional linear sub space.

Spectral Biclustering of Microarray Data: Coclustering Genes and Conditions

TL;DR: This work develops a method that simultaneously clusters genes and conditions, finding distinctive "checkerboard" patterns in matrices of gene expression data, if they exist, and applies it to a selection of publicly available cancer expression data sets.
