20090080773 | Image segmentation using dynamic color gradient threshold, texture, and multimodal-merging - A method for segmenting an image receives the image. The image has a number of pixels and a number of color channels. The image is initially segmented into a number of initial regions at least by dynamically selecting a plurality of seeds within the image using a dynamic color gradient threshold and growing the initial regions from the seeds until the initial regions encompass all the pixels of the image. A texture channel of the image is generated at least by applying an entropy filter to each of a plurality of quantized colors of the image. The initial regions into which the image has been initially segmented are multimodal-merged based on the color channels and the texture channel of the image, to yield a number of merged regions corresponding to segmentation of the image. | 03-26-2009 |
20100085605 | LOSSLESS COMPRESSION OF COLOR LOOK-UP TABLE VIA HIERARCHICAL DIFFERENTIAL ENCODING OR CELLULAR INTERPOLATIVE PREDICTION - A color look-up table (CLUT) is compressed in a lossless manner. The CLUT includes nodes that convert values of a first color space to corresponding values of a second color space. The CLUT is received in a serialized node-by-node manner. For each of some of the nodes the following is performed in the order in which the nodes are received in the serialized node-by-node manner. First, a difference value is determined that represents compression of a value of the node, in accordance with a hierarchical differential encoding approach or in accordance with a cellular interpolative prediction approach. Second, the difference value is stored in lieu of the value of the node being stored, to compress the value of the node in the lossless manner. | 04-08-2010 |
20100183225 | Methods for adaptive and progressive gradient-based multi-resolution color image segmentation and systems thereof - A multi-resolution color image segmentation algorithm which takes advantage of gradient information in an adaptive and progressive framework is described. A gradient-based segmentation method is initiated with a dyadic wavelet decomposition scheme of an arbitrary input image, accompanied by a vector gradient calculation of its color converted counterpart. The resultant gradient map is used to automatically and adaptively generate thresholds for segregating regions of varying gradient densities, at different resolution levels of the input image pyramid. In combination with a confidence map and non-linear spatial filtering techniques, regions of high confidence are passed from one resolution level to another until the final segmentation at highest (original) resolution is achieved. | 07-22-2010 |
20130027752 | CREATING AN IMAGE TO BE PRINTED USING HALFTONE BLENDING - A method for creating an image to be printed is provided. A first halftone pattern and a second halftone pattern for respective first and second periodic clustered dot halftone regions of the image are selected. The regions have respective frequencies and one of the frequencies is higher than the other frequency. A transition region is determined. The transition region includes a boundary between the two regions and includes additional portions of the two regions beyond the boundary. The two halftone patterns are blended with each other in the transition region based on a blending ratio of the two halftones where the blending ratio changes as a function of distance between the edges of the transition region. | 01-31-2013 |

20130120931 | ENCLOSING ARRANGEMENT OF RACKS IN A DATACENTER - Enclosing arrangements of racks of computing devices fully encloses a space, either solely by the racks themselves, or in conjunction with structural features, such as walls and doors. The enclosed space can be either a hot aisle, whose hot air is vented out by fans positioned in at least one vertical extremity of the enclosed space, such as the floor, or ceiling, or it can be a cold aisle, whose cold air is pumped in by those fans. To maintain proper pressurization across a vertical cross-section of the enclosed space, specific ones of the computing devices have their fans adjusted based on their vertical position within the racks or have passive airflow adjustments, such as impedance screens. Computing devices can draw or vent air from their sides, taking advantage of the interstitial space between the racks provided by the enclosing arrangement. | 05-16-2013 |
20130282944 | SAS INTEGRATION WITH TRAY AND MIDPLANE SERVER ARCHITECTURE - In computing scenarios involving multiple computational units, an enclosure (e.g., a rack or server cabinet) may store the units and provide resources such as shared power and network connectivity. Additionally, the components of the units may communicate through a Serial Attached SCSI (SAS) bus, but many such enclosures provide little or no integration with the SAS buses, thus entailing extensive SCSI cabling. Presented herein are architectures for enclosures presenting a set of slots for trays storing respective computing blades, where such trays include SAS connectors that connect directly (i.e., without cabling) with connectors on a midplane that interconnects the blades into a SAS bus featuring at least one integrated SAS expander. Additional architectural variations involve providing SAS expander on one or both of the midplane and the blades; grouping blades into subsets having distinct SAS buses; and interconnecting the SAS buses and expanders of multiple midplanes in the enclosure. | 10-24-2013 |
20130335907 | TRAY AND CHASSIS BLADE SERVER ARCHITECTURE - In computing scenarios involving an aggregation of multiple computational units into a server or computer set, many architectures may be devised to provide physical storage and logical aggregation of the computational units. Presented herein are variations of one such architecture, comprising a chassis having a set of slots, into which may be inserted a tray storing the computational units of one or more blades. Respective trays and chassis slots comprise a power connector and a network connector that are positioned to connect directly (i.e., without a cable or manual interaction) when a tray is inserted into a slot. The chassis stores a set of power supplies, and may connect each blade with a power supply, optionally providing power routing and failover capabilities. The chassis may also provide a management component that connects to and provides management capabilities of the blades of the trays, power supplies, and climate regulating components. | 12-19-2013 |
20130344794 | CLIMATE REGULATOR CONTROL FOR DEVICE ENCLOSURES - Climate regulation within an enclosure (e.g., a case of a workstation or a rack or cabinet of servers) may be achieved through a climate regulator featuring several selectable climate regulator settings (e.g., a variable-speed fan array). Controllers of such climate regulators often select climate regulator settings based on current conditions inside the enclosure, such as the temperature of one or more processors operating within the enclosure. However, such control fails to account for the climate of air outside the enclosure that is drawn in to provide climate regulation, even though the climate properties of inlet air may significantly affect the effectiveness of climate regulation. Accordingly, a controller of a climate regulator may be configured to detect inlet climate properties of air directed into the enclosure, and to map the inlet climate properties (alone or in combination with other factors) to a selected climate regulator setting for the climate regulator. | 12-26-2013 |
