摘要： When a scene moves homogeneously or fast, human eyes become sensitive to freezing artifacts. To measure the strength of motion homogeneity, a panning homogeneity parameter is estimated to account for isotropic motion vectors, for example, caused by camera panning, tilting, and translation, a zooming homogeneity 5 parameter is estimated for radial symmetric motion vectors, for example, caused by camera zooming, and a rotation homogeneity parameter is estimated for rotational symmetric motion vectors, for example, caused by camera rotation. Subsequently, an overall motion homogeneity parameter is estimate based on the panning, zooming, and rotation homogeneity parameters. A freezing distortion factor can then 10 be estimated using the overall motion homogeneity parameter. The freezing distortion factor, combined with compression and slicing distortion factors, can be used to estimate a video quality metric.

摘要： 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.

摘要： 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.

摘要： A particular implementation receives a bitstream and derives parameters from the bitstream. The parameters include quantization parameters, content unpredictability parameters, ratios of lost blocks, ratios of propagated blocks, error concealment distances, motion vectors, durations of freezing, and frame rates. Using these parameters, a compression distortion factor, a slicing distortion factor, and a freezing distortion factor are estimated respectively for distortions resulting from video compression, a slicing mode error concealment, and a freezing slicing mode error concealment. The distortion factors are then mapped to a composite video quality score. For applications with limited computational power, the estimation of distortion factors can be simplified. In particular, the compression distortion factor, the slicing distortion factor, and the freezing distortion factor can be predicted from quantization parameters, ratios of lost blocks, and durations of freezing, respectively.

摘要： A particular implementation forms an initial reconstructed image block from inverse quantization and inverse transform, and further refines the reconstructed image block using pixels from neighboring reconstructed blocks. The image block may be refined using a bilateral filter, whose space parameter and range parameter are adaptive to the quantization parameter. The particular implementation can be used in both encoding and decoding when reconstructing an image block. When used in encoding, the particular implementation can be used jointly with coefficient truncation, where some non-zero transform coefficients are set to zero. The number of remaining non-zero transform coefficients after coefficient truncation may be adaptive to the quantization parameter, the variance of the image block, the number of non-zero transform coefficients of the image block, and the index of the last non- zero transform coefficient in a zigzag scanning order.
