摘要： Methods for registering first and second images which are offset by an x and/or y displacement in sub-pixel locations are provided. A preferred implementation of the methods includes the steps of: multiplying the first image by a window function to create a first windowed image; transforming the first windowed image with a Fourier transform to create a first image Fourier transform; multiplying the second image by the window function to create a second windowed image; transforming the second windowed image with a Fourier transform to create a second image Fourier transform; computing a collection of coordinate pairs from the first and second image Fourier transforms such that at each coordinate pair the values of the first and second image Fourier transforms are likely to have very little aliasing noise; computing an estimate of a linear Fourier phase relation between the-first and second image Fourier transforms using the Fourier phases of the first and second image Fourier transforms at the coordinate pairs in a minimum-least squares sense; and computing the displacements in the x and/or y directions from the linear Fourier phase relationship. Also provided are a computer program having computer readable program code and program storage device having a program of instructions for executing and performing the methods of the present invention, respectively.

摘要： A multiresolution method and apparatus for searching of a database of images where the search is performed on compressed images, without first decompressing them. The method searches the database of compressed images first at a low resolution to obtain the relative quality of a match between a search template and a candidate image. If the match is below a particular threshold, the search is terminated without committing any further computational resources to the search. Conversely, if the match is above a particular threshold, the method enhances the resolution of the candidate image and then performs another match. As long as the relative quality of the match is above the particular threshold, the resolution of the candidate image is successively enhanced, until a match determination is made at a full resolution of the candidate image.

摘要： The invention is a system and method for improving the signal-to-noise ratio of an electrical data signal transmitted between two electronic modules. An electrical data signal from a first module is amplified by an electrical amplifier to produce an amplified electrical data signal. The electrical amplifier is supplied by a power distribution network. The amplified electrical data signal has a power level sufficiently low such that the electrical amplifier does not cause significant disturbances in the power distribution network so that a plurality of the electrical amplifiers can be proximately located and operated concurrently without significant noise coupling occurring between the electrical amplifiers through the power distribution network. The electrical data signal is then converted to an optical data signal for transmission to a second module. The optical data signal is transmitted to the second module through an optical path where it is optically amplified. The amplified optical data signal is then received at the second module and detected to produce an electrical signal which has a substantially improved signal-to-noise ratio.

This reduces the access requests and subsequent contention caused by multiple concurrent requests to a common variable.

摘要： This invention enables progressively higher resolution images of a JPEG compressed image to be produced in a cost effective manner during the JPEG decompression process. The operation count is very low when images of {fraction (1/64)}th, {fraction (1/16)}th, and ¼th of full resolution are to be produced without doing a full JPEG decompression. The low resolution images are useful for high speed search, and the ability to produce them without doing full decompression is an important factor in making such search practical.

摘要： A computer-implemented process for determining a ranked set of solutions to a bipartite graph matching problem, such is involved in multi-target tracking, maximum flow matching, or data association in matching elements of a first set to elements of a second set to minimize the cost of the association. A feature of the process is a partitioning into subproblems such that the most probable solutions are in the smaller subproblems and the computation begins by solving the smallest subproblem in the search for the best solution.

摘要： A Write/Load cache protocol is described which may be used for maintaining cache coherency and performing barrier synchronization in multiprocessor computer systems, and for cooperating with prefetch mechanisms to allow data to be loaded into a central processor unit's (CPU) cache (in both single and multiprocessor systems) in anticipation of future memory references. The new protocol is defined such that when a cache observes a Write/Load command (and associated data item) on a bus to which the cache is attached, the cache is accessed and (a) if the data item is in the cache, the new value of the data item from the bus is copied into and replaces the data item in cache; and (b) if the data item is not in the cache, a new data item is created therein (preferably using the normal cache replacement policy), and the value of the data item on the bus is loaded into the cache. Thus, a protocol is provided which allows cache to be loaded via an external entity, i.e., other than the processor being directly serviced by the cache.

摘要： An optical bus for interconnecting electronic devices. The bus has a substrate with through-holes therein. An optically conductive material is disposed on one side of the substrate. The material fills the through-holes and forms a layer of predetermined thickness on this side of the substrate. In the outer surface of this layer there are facets or angled regions. The surface and facets are optically reflective. Cards or modules are optically connected by means of optical connectors to the through-holes on the opposite side of the substrate. Light emitted by the connector travels to the associated faceted surface from which it reflects towards other faceted surfaces from which it is partially transmitted and partially reflected to another connector. The arrangement permits optical communication between a plurality of electronic devices.
