We propose illumination invariant face recognition and 3D face reconstruction using desktop optics. The computer screen is used as a programmable extended light source to illuminate the face from different directions and acquire images. Features are extracted from these images and projected to multiple linear subspaces in an effort to preserve unique(More)
Hyperspectral video acquisition is a trade-off between spectral and temporal resolution. We present an algorithm for recovering dense hyperspectral video of dynamic scenes from a few measured multispectral bands per frame using optical flow and sparse coding. Different set of bands are measured in each video frame and optical flow is used to register them.(More)

We present an algorithm for 3D face reconstruction from multiple images under arbitrary illumination. A computer screen is used to illuminate a face from different angles. Three images under different illuminations are used to compute its basis vectors using SVD. The first basis vectors from training faces are projected to a PCA subspace and used as input(More)
This paper aims to scrutinize how the organizational culture impacts knowledge activities and learning in project-based industry. The extent to which organizational culture influences knowledge activities and ultimately the performance of the project-based organization is investigated in the study. Firstly, the concept of knowledge and organizational(More)
Quantification of sun-related changes in conjunctival ultraviolet autofluorescence (CUVAF) images is a subjective and tedious task, in which reproducibility of results is difficult. Thus, we have developed a semiautomatic method in MATLAB(®) to analyze CUVAF images retrospectively. The algorithm was validated on 200 images from 50 randomly selected(More)
We propose Human Pose Models that represent RGB and depth images of human poses independent of clothing textures, backgrounds, lighting conditions, body shapes and camera viewpoints. Learning such universal models requires training images where all factors are varied for every human pose. Capturing such data is prohibitively expensive. Therefore, we develop(More)
