A multiple camera tracking system for interfacing with an application program running on a computer is provided. The tracking system includes two or more video cameras arranged to provide different viewpoints of a region of interest, and are operable to produce a series of video images. A processor is operable to receive the series of video images and detect objects appearing in the region of interest. The processor executes a process to generate a background data set from the video images, generate an image data set for each received video image, compare each image data set to the background data set to produce a difference map for each image data set, detect a relative position of an object of interest within each difference map, and produce an absolute position of the object of interest from the relative positions of the object of interest and map the absolute position to a position indicator associated with the application program.

Analysis of multi-spectral data for extraction of chlorophyll content. Multi-spectral data is obtained from an imaging device. The multi-spectral data contains spectral response data for chlorophyll and background data. The background data is removed from the multi-spectral data to isolate the spectral response due only to chlorophyll. This is then presented as a chlorophyll absorption feature which may be analyzed by measuring the width of the feature, the surface area of the feature, or measuring various angular changes of the feature. These measurements may than be used for a variety of purposes including plant health analysis.

Part of the latency from memory read or write operations is for data to be input to or output from the data latches of the memory via an I/O bus. Methods and circuitry are present for improving performance in non-volatile memory devices by allowing the memory to perform some of these data caching and transfer operations in the background while the memory core is busy with a read operation. A scheme for caching read data is implemented so that even when the read for a current page on a current wordline must be preceded by a prerequisite read of data on an adjacent wordline, the prerequisite read along with any I/O access is preemptively done in the cycle for reading a previous page so that the current read can be performed while the previously read page is busy with the I/O access.

In the driving of a liquid crystal display panel with pixels in a matrix comprising n rows and m columns, when a partial display instruction is issued, respective rows in a display area (202) of s rows and m columns within the matrix are sequentially selected for one frame. Then, predetermined partial display data is written into the selected rows. Predetermined background data such as white display data is written into the background area (204) other than the partial display area (202). In the background area 204, either k rows and m columns or pixels of (the leading row ((s+1)-th row) of the background area, next to the final row in the partial display area) are selected during one frame for writing of the background display data, k rows and m columns are sequentially shifted each frame.

A system, computer program product and method for a running process migration with planned minimized down-time. The method facilitates fast and efficient process migration by performing background data synchronization prior to actual process migration. The service slowdown is reduced by employing two-stage transfer method. During a first stage the service, being executed on the original machine, does not stop and all the available data required by this process is being copied. After the first stage is completed the service continues to be executed without an interruption, while the most of the data associated with the service process is already transferred to the new machine. During the second stage the execution of the service on the first machine is stopped. The files, which were not available during the first stage, are now copied. Then the execution of service is started on the second machine. The down-time is reduced to the duration of the second stage.

A method and apparatus for detecting a target or targets in a surrounding background locale based on target signatures obtained by a hyperspectral imaging sensor used the hyperspectral imaging sensor to collect raw target signature data and background locale data during a first data collection mission. The data is processed to generate a database including a plurality of target signatures and background data relating to the background locale. The hyperspectral imaging sensor is later used to collect further background data during a further, current data collecting mission so as to provide continuously updated background data, in real time. A covariance equalization algorithm is implemented with respect to the background data contained in the database and the updated background data collected during the current mission to effect transformation of each target signature of the database into a transformed target signature. A detection algorithm which employs the resultant transformed target signature is used to produce detection information related to the target or targets.

A library of available incentive programs is established for an agricultural product. Input is accepted from an agricultural producer or a crop planner to facilitate tailoring the library of incentive programs to the requirements (e.g., needs, objectives, and resources) of a particular producer. The library of available incentive programs is searched based upon the accepted input to select a tailored list of candidate incentive programs from the library. Information on the tailored candidate incentive programs is made accessible to the agricultural producer. The agricultural producer may select a preferential incentive program between or among the candidate incentive programs. Further, the producer may readily seek financing via electronic communications to purchase or otherwise conduct a transaction under the preferential incentive program. If the producer applies for a financial product for financing the transaction under the preferential incentive program, the previously gathered input (e.g., background data on the particular producer) is transferred to a financial screening process to reduce duplicative reentry of data and to reduce or eliminate potential clerical errors.

The method and system for vehicular guidance comprises an imaging device for collecting color image data to facilitate distinguishing crop image data (e.g., crop rows) from background data. A definer defines a series of scan line segments generally perpendicular to a transverse axis of the vehicle or of the imaging device. An image parameter evaluator determines scan line image parameter data for each of the scan line segments. An alignment detector (e.g., search engine) identifies a preferential heading of the vehicle that is generally aligned with respect to a crop feature, associated with the crop image data, based on the determined scan line image parameter meeting or exceeding a maximum value or minimum threshold value. A reliability estimator estimates a reliability of the vehicle heading based on compliance with a criteria for scan line image parameter data associated with one or more crop rows.
