20110188860 | ELECTRICAL EQUALIZING PROCESSING METHOD AND DEVICE FOR OPTICAL SIGNAL AND OPTICAL FIBER COMMUNICATION SYSTEM - The electrical equalizing processing method for optical signal includes the following steps. An input optical signal is split into N channels of optical signals, in which N is an integer greater or equal to 2; band-pass filtering is performed on the split N channels of optical signals, in which central frequencies of a frequency band used in the performing of band-pass filtering on the N channels of optical signals are not exactly the same, and a passband of the frequency band and a frequency spectrum range of the N channels of optical signals overlap; the N channels of optical signals on which band-pass filtering is performed are converted into corresponding N channels of an analog electrical signal; an electrical equalizing process is performed on the N channels of the analog electrical signal to output an optical signal electrical equalizing processing result. | 08-04-2011 |

20140037223 | METHOD AND DEVICE FOR LOSSY COMPRESS-ENCODING DATA AND CORRESPONDING METHOD AND DEVICE FOR RECONSTRUCTING DATA - The invention proposes modification of quantized coefficients for signalling of a post-processing method. Therefore, it is proposed a method for lossy compress-encoding data comprising at least one of image data and audio data. Said method comprises determining quantized coefficients using a quantization of a discrete cosine transformed residual of a prediction of said data. Said method further comprises modifying said quantized coefficients for minimizing rate-distortion cost wherein distortion is determined using a post-processed reconstruction of the data, the post-processed reconstruction being post-processed according to a post | 02-06-2014 |
20140040999 | HYBRID MULTI-TENANCY CLOUD PLATFORM - Technologies are presented for a hybrid cloud-based service model combining separate database/separate schema, shared database/separate schema, and shared database/shared schema architectures suitable for serving multiple tenants while addressing varying security needs. Roles and security level needs of different tenants may be determined based on tenant declaration or inference from tenant attributes. Tenants may then be assigned to suitable clouds or sub-clouds based on their security level needs. In some examples, a claims-based access control authorization model such as federation may be employed to support interactions between the three different types of clouds or sub-clouds under the umbrella of a single cloud-based service provider while maintaining application and data security. | 02-06-2014 |

20140301486 | VIDEO QUALITY ASSESSMENT CONSIDERING SCENE CUT ARTIFACTS - A particular implementation detects scene cut artifacts in a bitstream without reconstructing the video. A scene cut artifact is usually observed in the decoded video (1) when a scene cut picture in the original video is partially received or (2) when a picture refers to a lost scene cut picture in the original video. To detect scene cut artifacts, candidate scene cut pictures are first selected and scene cut artifact detection is then performed on the candidate pictures. When a block is determined to have a scene cut artifact, a lowest quality level is assigned to the block. | 10-09-2014 |
20140301649 | TEXTURE MASKING FOR VIDEO QUALITY MEASUREMENT - A particular implementation decomposes an image into a structure component and a texture component. An edge strength map is calculated for the structure component, and a texture strength map is calculated for the texture component. Using the edge strength and the texture strength, texture masking weights are calculated. The stronger the texture strength is, or the weaker the edge strength is, the more distortion can be tolerated by human eyes, and thus, the smaller the texture masking weight is. The local distortions are then weighted by the texture masking weights to generate an overall distortion level or an overall quality metric. | 10-09-2014 |
20140307955 | APPARATUS AND METHOD FOR DETECTING BODY PARTS FROM USER IMAGE - An apparatus for detecting a body part from a user image may include an image acquirer to acquire a depth image, an extractor to extract the user image from a foreground of the acquired depth image, and a body part detector to detect the body part from the user image, using a classifier trained based on at least one of a single-user image sample and a multi-user image sample. The single-user image may be an image representing non-overlapping users, and the multi-user image may be an image representing overlapping users. | 10-16-2014 |
20140334555 | METHOD AND APPARATUS FOR VIDEO QUALITY MEASUREMENT - Accuracy and efficiency of video quality measurement are major problems to be solved. According to the invention, a method for accurately predicting video quality uses a rational function of the quantization parameter QP, which is corrected by a correction function that depends on content unpredictability CU. Exemplarily, the correction function is a power function of the CU. Both QP and CU can be computed from the video elementary stream, without full decoding the video. This ensures high efficiency. | 11-13-2014 |
20150023495 | CHANGE-TOLERANT METHOD FOR GENERATING IDENTIFIER FOR COLLECTION OF ASSETS IN COMPUTING ENVIRONMENT USING ERROR-CORRECTION CODE SCHEME - A secure and change-tolerant method for obtaining an identifier for a collection of assets associated with a computing environment. Each asset has an asset parameter and the computing environment has a fingerprint based on an original collection of assets and on a codeword generation algorithm on the original collection of assets. The method comprises: retrieving the asset parameters of the collection of assets and processing the retrieved asset parameters to obtain code symbols. An error-correction algorithm is applied to the code symbols to obtain the identifier. The method can be used in node-locking. | 01-22-2015 |
