in the recent years, considerable attention has been allocated in the area of using natural preservatives in foods, especially vegetable oils.  starch foams prepared from high amylose starch are useful for encapsulation of substances such as chemicals, liquids or solids, including flavor compounds, pharmaceuticals and essential oils. the foams have the ability to trap the active material and su...

The goal of active vision is to change intrinsic or extrinsic properties of the sensor in order to get new and improved information. In the case of 3-D object modeling from vision, this can mean moving the camera to view the scene from a new angle or to get a close-up view of an object that has been localized and is being modeled. We discuss using active vision to improve the speed and utility ...
