Features detection and description among multiple images are widely used in many applications, e.g., feature matching, object categorization, 3D construction, image retrieval and object recognition. This paper evaluates combination performance of different feature detectors and descriptors. It will compare performance of detectors and descriptors combination on images under rotate, scale constr...
We show how it is possible to controllably rotate or align microscopic particles of isotropic nonabsorbing material in a TEM00 Gaussian beam trap, with simultaneous measurement of the applied torque using purely optical means. This is a simple and general method of rotation, requiring only that the particle is elongated along one direction. Thus, this method can be used to rotate or align a wid...
The precise rotational manipulation of single cells or organisms is invaluable to many applications in biology, chemistry, physics and medicine. In this article, we describe an acoustic-based, on-chip manipulation method that can rotate single microparticles, cells and organisms. To achieve this, we trapped microbubbles within predefined sidewall microcavities inside a microchannel. In an acous...
