20100017545 | Method for Empirically Determining a Qualified Bandwidth of File Storage for a Shared Filed System - A method for preventing oversubscription to a file storage by multiple processes, whether such processes are operating on one node with directly attached storage or on several nodes of a computing cluster sharing a storage area network. Processes or nodes issue requests for bandwidth reservations to a controller daemon. The controller daemon maintains records of all existing bandwidth reservations and ensures that new reservations are granted only if a qualified bandwidth of the file storage will not be exceeded. The qualified bandwidth is empirically determined to take into account installation specific hardware configurations, workloads, and quality of service requirements. In conjunction with suitable enabled client kernels the controller daemon serves to encapsulate all I/O activity including non-reserved I/O activity to the file storage by issuing non-guaranteed bandwidth leases for use by each node in servicing non-guaranteed process I/O activity, such leases being revokable by the controller daemon in order to service new guaranteed bandwidth reservation requests. | 01-21-2010 |

20100157340 | OBJECT EXTRACTION IN COLOUR COMPOUND DOCUMENTS - Disclosed is a computer implemented method of text extraction in colour compound documents. The method connects similarly coloured pixels of an image of a colour compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global colour context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local colour context statistics to thereby provide the extracted text in the text blocks. Also disclosed is a computer implemented method of locating graphics objects in a colour compound document image. The method connects similarly coloured pixels of said image into connected components (CCs) and placing the CCs in an enclosure tree; classifies ( | 06-24-2010 |
