Dark shadows of medicine

Out of the Dark: Using Shadows to Reconstruct

Shape From Darkness refers to using the shadows cast by a scene to reconstruct the structure of the scene. A collection of images associated with di erent light source positions is used. Previously published solutions to this problem have performed the reconstruction only for cross sections of the scene. We propose a variant of Shape From Darkness which is capable of reconstructing the entire 3...

Induction The dance of shadows

Statistics stems out from induction. Induction is a long lasting notion in philosophy. The nature of notions in philosophy are such that neither they can be solved completely nor one can leave them forever. One of the most important problem in induction is “the problem of induction”. In this paper we give a short history of induction and discuss some aspects of the problem of induction.  

The dark side of evidence-based medicine.

Shadows.

We investigate the brightness distribution in and around outdoor shadows (for a variety of sky conditions) using modeling and field measurements. The dominant factor influencing the brightness of a shadow is the solid angle subtended by the object blocking the Sun. Occulters at the zenith that subtend a small solid angle cast shadows that are bright and possess a nearly uniform brightness acros...
