A powerful, scaleable, and reconfigurable image processing system and method of processing data therein is described. This general purpose, reconfigurable engine with toroidal topology, distributed memory, and wide bandwidth I/O are capable of solving real applications at real-time speeds. The reconfigurable image processing system can be optimized to efficiently perform specialized computations, such as real-time video and audio processing. This reconfigurable image processing system provides high performance via high computational density, high memory bandwidth, and high I/O bandwidth. Generally, the reconfigurable image processing system and its control structure include a homogeneous array of 16 field programmable gate arrays (FPGA) and 16 static random access memories (SRAM) arranged in a partial torus configuration. The reconfigurable image processing system also includes a PCI bus interface chip, a clock control chip, and a datapath chip. It can be implemented in a single board. It receives data from its external environment, computes correspondence, and uses the results of the correspondence computations for various post-processing industrial applications. The reconfigurable image processing system determines correspondence by using non-parametric local transforms followed by correlation. These non-parametric local transforms include the census and rank transforms. Other embodiments involve a combination of correspondence, rectification, a left-right consistency check, and the application of an interest operator.

Speaker recognition is attempted on input speech signals concurrently with provision of input speech signals to a speech recognition system. If a speaker is recognized, a speaker dependent model which has been trained on an enrolled speaker is supplied to the speech recognition system. If not recognized, then a speaker-independent recognition model is used or, alternatively, the new speaker is enrolled. Other speaker specific information such as a special language model, grammar, vocabulary, a dictionary, a list of names, a language and speaker dependent preferences can also be provided to improve the speech recognition function or even configure or customize the speech recognition system or the response of any system such as a computer or network controlled in response thereto. A consistency check in the form of a decision tree is preferably provided to accelerate the speaker recognition process and increase the accuracy thereof. Further training of a model and/or enrollment of additional speakers may be initiated upon completion of speaker recognition and/or adaptively upon each speaker utterance.

Feature vectors representing each of a plurality of overlapping frames of an arbitrary, text independent speech signal are computed and compared to vector parameters and variances stored as codewords in one or more codebooks corresponding to each of one or more enrolled users to provide speaker dependent information for speech recognition and/or ambiguity resolution. Other information such as aliases and preferences of each enrolled user may also be enrolled and stored, for example, in a database. Correspondence of the feature vectors may be ranked by closeness of correspondence to a codeword entry and the number of frames corresponding to each codebook are accumulated or counted to identify a potential enrolled speaker. The differences between the parameters of the feature vectors and codewords in the codebooks can be used to identify a new speaker and an enrollment procedure can be initiated. Continuous authorization and access control can be carried out based on any utterance either by verification of the authorization of a speaker of a recognized command or comparison with authorized commands for the recognized speaker. Text independence also permits coherence checks to be carried out for commands to validate the recognition process.

One or more requirements of a target hosting environment are captured in a specification. The specification is automatically checked against a source content of a source environment with a conformance checker, where the source content is to be migrated to the target hosting environment. It is determined whether the source content conforms to the specification.

In distributed storage environments, nodes may send replicated writes for temporal volumes and may be configured to request on-demand consistency intervals in order to allow multiple nodes to transition between timestamps for temporal data in a uniform and coordinated manner. In response to a request from a node for a consistency interval transition, a consistency interval coordinator may end a current consistency interval and start another and may provide coordination to various nodes to enable the nodes to transition from one timestamp to another, and thus from one temporal version to another, while prevent data corruption or inconsistency between the temporal versions. Additionally, periodic consistency intervals may be utilized to provide consistent and coordinated transitions between temporal timestamps. In some embodiments, replicated writes including temporal timestamp information may be stored persistent spillover logs allowing offline updating and versioning of data to temporal volumes.

A method for performing a consistency check on a database backup of a database is performed without requiring a full recovery of the original database from the database backup. Instead, a database view may be used as a smaller storage requirement tool for providing a transaction-consistent view of portions of an existing full database backup. The database view, in combination with the database backup and transaction log, contains all the information necessary to perform a consistency check on the database backup without a full reconstitution of the original database from the database backup. The consistency check may be run on the database view along with the database backup to verify the integrity of the full database backup to add improved reliability to a database recovery scheme.

A system and method for efficiently detecting and correcting transmission errors in packet-based communications by using cumulative error detection codes. The system may comprise a transmitting unit, which transmits one or more data packets. Each of the transmitted packets may comprise a plurality of transmission subunits. The transmitting unit preferably generates a cumulative error detection code (e.g., cumulative CRC code) for each of the transmission subunits of a packet. The system may further comprise a receiving unit to receive each of the transmission subunits of the packet. The receiving unit preferably generates a new cumulative error detection code for each of the received transmission subunits. The new cumulative error detection code is compared to the received cumulative error detection code to determine if any errors occurred in the transmission of the transmission subunit.

A system and method for performing a distributed consistency check of a clustered file system. File system functions for loading an inode and/or buffer tree are modified so that in response to either of these functions being invoked, a consistency check is performed. The consistency check verifies both local consistency on a node of the clustered file and a distributed check across the nodes of the storage system

A method, system computer-readable medium and software arrangement are provided for processing a device support file for a field device, such as a Foundation™ Fieldbus device. A device support file can be installed on a processing arrangement. The device support file may be received, for example, from a remote computer system. In one exemplary embodiment, a configuration file may be opened and reviewed to identify any missing device support files, and the missing files may be obtained automatically from the remote computer system. Upon the installation, a capabilities file of the device support file may be validated by comparing the capabilities file with common (previously obtained) rules generally associated with the capabilities file. In one further exemplary embodiment, the capabilities file may be validated by performing a consistency check of the retrieved capabilities file with a current version of the common rules.

A method and system are provided for processing a document comprising a plurality of content portions. The document includes code identifying tasks corresponding to at least one content portion of the document, and code defining an associated user interface element. When the user interface element is activated to invoke the task, tasks to be executed by a remote system are executed by the remote system using a remotely stored copy of the associated content portion, while tasks to be executed by a local system are executed by the local system using a locally stored copy of the content portion. Changes to at least certain portions of the document are synchronized between the local and remote servers. The tasks can include a consistency-checking task for verifying consistency of certain content within the document, and display of results with optional suggested corrections to permit manual or automatic correction of detected discrepancies.

Testing a display involves display of a series of test patterns, each at a different luminance or colour, and with a predetermined minimum difference of luminance or colour from their background, each pattern being unpredictable to a user, and determining if the user has correctly identified the patterns. This can enable a more objective test without needing external measuring equipment. Calibrating the display involves determining an output luminance level by detecting a minimal difference of drive signal to give a just noticeable output luminance difference at a given high luminance drive level, and determining an absolute luminance of the given high input luminance level from the minimal difference and from a predetermined human characteristic of visibility threshold of luminance changes. This can avoid the need for an external or internal sensor. This can be useful during conformance checks or during calibration of the display for example.

According to one implementation, the mirror consistency check procedure may be implemented using the consistency information stored at the mirror consistency data structure.

A computer network comprising a plurality of terminals (1–4) connected via a communications network 5 is provided. In each of the terminals (1–4) application software (15) for generating XML source documents is provided. XML source documents created using the application software (15) are then sent to one of the terminals (4) having stored therein a consistency checker (10). The consistency checker (10) processes the source document together with a set of consistency rules (14) to generate an output presentation identifying data within the source documents which does or does not fulfil the requirements of consistency relationships defined by the consistency rules (14).

Inconsistencies between configuration rules represent a significant concern when modeling a product using configuration rules. The consistency checking system approaches a configuration model from the perspective of a sets of features and families. The configuration space of a model represents the entire set of all combinations of selections within a configuration model. The consistency checking system operates on subsets of the configuration space by consolidating data within the configuration space into minimized subsets that represent a portion of the configuration space where a particular consistency error can occur. Thus, the contents of each subset vary depending upon which consistency error is being checked, and consistency checking is performed on reduced subsets determined on an error by error basis rather than on the configuration space as a whole.

Attribute consistency works on the comparison of a reference value against the online value of the attributes, which are retrieved from the corresponding system. In order to know which attributes need to be considered for consistency, a list of relevant attributes of each entity type in each application is stored together with the reference value of the entity. This attribute list is used by the consistency service. Therefore several attribute values of one entity in one system can be included in a combined “hash” value. At start-up or in the engineering phase, this reference value is computed out of the defined attribute list. At the time of a consistency check, the values of the attributes are read and a “hash” value is calculated with the same algorithm as the reference value. If those two values differ, an inconsistency occurred. The inventive method allows validating consistency of attributes of an entity in one of the participating applications. Any inconsistency can be propagated to all other participating applications which then may trigger functionality accordingly.

The invention provides a three-dimensional matching method based on union similarity measure and self-adaptive support weighting. The method comprises the following specific steps: (1) correcting an obtained left and right image as a standard image through a correction algorithm; (2) carrying out the three-dimensional matching cost calculation by using the local union phase similarity so as to obtain initial pixel-based matching cost; (3) setting a support weighting for each pixel in a support domain by using a self-adaptive support weighting algorithm, and filtering by using a guide filter so as to obtain smooth matching cost based on a support domain window; (4) selecting a parallax value as a parallax value of the pixel by using a WTA principle while the matching cost value is minimum; (5) carrying out the left and right consistency check and replacing invalid parallax values and filtering; and (6) calculating a depth value of a target object. The method can be applied to fields of computer vision, robot navigation, mode recognition, medical diagnosis, industrial detection, military application, aerial plotting and the like.
