Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Active Implicit Surface for Animation

This paper introduces a new model of deformable surfaces designed for animation, which we call active implicit surfaces. The underlying idea is to animate a potential field defined by discrete values stored in a grid, rather than directly animating a surface. This surface, defined as an iso-potential of the field, has the ability to follow a given object using a snake-like strategy. Surface ten...

Active Stereo Based Surface Reconstruction

This paper is concerned with the problem of surface reconstruction from stereo images for large scenes having large depth ranges. The passive stereo paradigm is inadequate for this problem because of the need to aim cameras in different directions and to fixate a t different objects. We present an active stereo approach in which the scene is systematically scanned and image acquisition and surf...
