摘要： The system and method described below allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating control signals in the scheme.

摘要： Certain embodiments relate to processing images by creating scale space images from an image and using them to identify boundaries of objects in the image. The scale space images can have varying levels of detail. They are used to determine a potential map, which represents a likelihood for pixels to be within or outside a boundary of an object. A label estimating an object boundary can be generated and used to identify pixels that potentially may be within the boundary. An image with object boundaries identified can be further processed before exhibition. For example, the images may be two-dimensional images of a motion picture. Object boundaries can be identified and the two-dimensional (2D) images can be processed using the identified object boundaries and converted to three-dimensional (3D) images for exhibition.

摘要： The invention relates to a method and an apparatus for processing an image to filter unwanted regions and extract a region of interest (e.g. the cervix region of a patient) based on speculum detection executed immediately after the image is captured, and to save the cervix region instead of a full image. Unwanted regions are removed and the image is cropped to be restricted to the region of interest, so that storage space can be saved. Thereby, workflow efficiency can be increased and storage space and transmission time can be reduced.
