摘要： A system and method for an efficient semantic similarity search of images with a classification structure are provided. The system and method provide for building a semantic classification-search tree for the plurality of images, the classification tree including at least two categories of images, each category of images representing a subset of the plurality of images, receiving a query image, classifying the query image to select one of the at least two categories of images, and restricting the search for the image of interest using the query image to the selected one of the at least two categories of images.

摘要： A JPEG2000 compressed image is transcoded to a lower bit-rate or lower resolution, or both, without having to decompress the initial JPEG2000 image and then recompress it to a lower bit-rate and/or resolution. Instead, arithmetic decoding is performed only to the nearest higher bit-rate layer, up to the desired resolution, before performing rate-distortion optimization to produce the transcoded image.

摘要： A system renders oblique slices through volumetric data accessed via a network using a client-server architecture. The system includes a server for processing and storing volumetric data comprising axial slices obtained from a diagnostic scanning system, a client for processing user requests related to specific views of the volumetric data, and a network protocol for connecting the client with the server over the network and obtaining data from the server for use by the client. A processing stage at the client specifies an oblique slice and communicates particulars of the oblique slice to the server, thereupon obtaining axial slice data from the server specifically for portions of the axial slices that are needed to render the oblique slice. Memory at the client stores the axial slice data, and a rendering stage at the client renders the oblique slice from the axial slice data in the memory.

摘要： A method for simultaneously recording motion and still images, includes the steps of: capturing a motion image sequence and accompanying audio of a scene with a digital video camera adapted to record both motion and higher resolution still images; simultaneously capturing a still image sequence having a higher resolution and lower frame rate than the motion capture sequence; compressing the motion image sequence using interframe compression and the accompanying audio and storing the compressed motion image and audio data; and compressing the still images using intraframe coding and storing the compressed still image data.
