Systems and methods of capturing high-resolution images of objects

InactiveUS20070291104A1high resolution
The invention relates to a system of capturing zoom-in images of an object. The system comprises a pan, tilt, zoom (PTZ) camera for capturing a video stream in view; an image-capture device for extracting and digitizing images from the video stream; an object detector for detecting objects in the images from the image-capture device, determining the locations and sizes of the objects and sending the locations and the sizes of the objects to a selector; the selector for determining one of the objects and sending the location and size of the one of the objects to a assessor; the assessor for determining the trajectories required to both align the one of the objects to the center of the image based on the current location of the one of the objects relative to the center and to maximize the size and resolution of the one of the objects according to the current size of the one of the objects, and for sending the trajectories to a translator; the translator for converting the trajectories into a signal stream with a command format that a camera controller can understand and for sending the converted trajectories to the camera controller; and the camera controller for moving and zooming the PTZ camera according to the signal stream, thereby the PTZ camera moves to center on the one of the objects and captures zoomed-in images of the one of the objects from the video stream.

Method and apparatus for creating a virtual microscope slide

InactiveUS20050254696A1reduce numberhigh resolution
A method and apparatus are disclosed for constructing a virtual microscope slide comprised of digitally scanned images from a microscope specimen. The digitally scanned images are arranged in a tiled format convenient for viewing without a microscope, and for transferring the tiled images for viewing by another at a remote location. Several original microscope views at a low magnification are digitized and stored as digitized images coherently seamed together to provide an overall virtual, macro image of the specimen at a lower resolution. Several original microscope views at higher magnifications are digitized and stored as digitized images coherently seamed together to provide virtual micro images at higher resolution. A data structure is formed with these virtual macro and micro digitized images along with their mapping coordinates. Preferably, a generic viewing program is also provided in the data structure that allows remote users to manipulate and interpret the tiled images on the user's monitor. Also, the data structure is formed with significantly compressed data so as to be transmitted over low bandwidth channels, such as the Internet, without loss of resolution that would interfere with the analysis at a remotely-located pathologist receiving the data structure over the Internet. The preferred interactive program allows the pathologist to scroll and view neighboring image areas of interest. A marker on the macro image indicates to the user the location of the micro image and assists the user in selecting areas from the macro image to be viewed at higher resolution and magnification.
