摘要:
Embodiments of the present invention provide a mechanism for converting an existing mirror relationship between an original dataset at a source storage system and a copy of the original dataset at a destination system to a new mirror without discarding the existing copy of the original dataset and without transferring data to create a new dataset to replace the copy of the original dataset at the destination storage system. Rather, a directory structure (including file attributes) of the source storage system is transferred to the destination storage system and a comparison is made to identify file attributes at the destination system that match the transferred file attributes. If a match is found, a mapping between the matched file attributes is created. Subsequent updates to the destination storage system can be done using a technique other than the one that was used to create a copy of the source dataset.

Systems and methods are presented for generating a new digital output image by blending a plurality of digital input images capturing the same scene at different levels of exposure. Each new pixel for the new digital output image is derived from a group of corresponding aligned pixels from the digital input images. For each group of corresponding pixels from the digital input images, an average color value in a first color space is derived by taking a separate average across each color channel of the first color space. The resulting average color value in the first color space is modified in order to raise its corresponding color saturation value in a second color space. The new pixel's color value in the first color space is set to the modified average color value.

Data is transferred over a network for storage purposes in a way that accommodates systems which are equipped to only handle a predetermined data block size. This is accomplished by transmitting the data using the same data block size regardless as to whether the data is compressed or not. In use, data to be transferred is identified on a first computer. Prior to being transferred to a second computer, it is determined whether the data is to be compressed. If it is determined that the data is not to be compressed, the data is subdivided into a plurality of data blocks with a predetermined size. If it is determined that the data is to be compressed, the data is compressed and subdivided into a plurality of data blocks with the predetermined size. Such data blocks are then transferred to the second computer via the network, for storing the data.

A system and method for verifying the consistency of mirrored data sets is provided. A verification module executed on a destination storage system transmits a list of desired persistent consistency point images (PCPIs) to a source destination storage system. The source destination storage system identifies a common subset of PCPIs and returns a list of the common subset to the destination. The destination initiates a separate connection for each PCPI in the common subset. The source then generates a data stream which is transmitted to the destination for use in verifying the PCPIs.

摘要:
Seamless image compositions may be created. A plurality of images may be received, one image being a base image and the remaining image or images being source images. A selection may be received of one or more regions of one or more of the sources images to be copied onto the base image. An input may be received setting a blend parameter for each of the selected regions. The plurality of images may be blended together into a composite image by matching image gradients across one or more seams of the composite image. The image gradients may be based on the blend parameters. In one embodiment, input may be received to set a modified blend parameter for at least one of the selected regions and the plurality of images may be re-blended into a composite image in a similar manner but using the modified blend parameter.

摘要:
Methods and apparatus for blending regions from multiple images to produce a blended image. An image blending module may obtain multiple digital images of a scene. A base image and a source image are selected, and a stroke is applied to the source image to indicate a desired region which is to be blended with the base image. A region in the source image is identified from the stroke using a segmentation technique such as a graph cut algorithm, and the identified region is blended with the corresponding region of the base image, for example using alpha blending. Additional strokes may be applied to the source image to select other regions to be blended with the base image. A different image may be selected as a source image, and a region from the different image may be selected for blending with the base image.
