Abstract: Distributed content-aware compression and decompression techniques are provided for data, such as seismic data. Data is compressed by obtaining a file chunk of a plurality of file chunks of a larger file, a start offset of the file chunk, and a data descriptor indicating how the file chunk should be processed based on characteristics of the larger file. Headers in the file chunk are compressed using a substantially lossless header compression technique to obtain compressed headers. Samples in the file chunk are compressed using a substantially lossless sample compression technique to obtain compressed samples. The compressed headers and compressed samples are packed into a single bit stream comprising a compressed version of the file chunk. The compression can be performed in a physical or logical layer of storage nodes of a file system or in compute nodes of a computing cluster. The compression can be executed on demand by an external agent and/or in a background mode by a storage operating system.

Abstract: This disclosure is directed to a touchless interactive environment. An input device may be configured to capture electronic images corresponding to physical objects detectable within a physical three-dimensional region. A computer system may establish a virtual three-dimensional region mapped to the physical three-dimensional region, with the virtual three-dimensional region defining a space where a plurality of virtual objects are instantiated based on the plurality of electronic images. The computer system may select a virtual object from the plurality of virtual objects as one or more commanding objects, with the one or more commanding objects indicating a command of a graphical user interface to be performed based on a position of the one or more commanding objects. The computer system may then perform the command of the graphical user interface based on the position of the one or more commanding objects.

Abstract: Methods and apparatus are provided for rational compression of numbers. One or more numbers are compressed by obtaining a plurality of numbers (e.g., integer numbers and/or floating point numbers), wherein each of the plurality of numbers is represented using zero or more bits to indicate an exponent at a given base of the given number and has a length representing a number of significant bits of the given number; for each of the plurality of numbers, obtaining a pair of values comprised of the length and the exponent and counting occurrences of the pair; generating a Huffman encoding comprising at least one Huffman tree based on the counting of the occurrences; generating one or more encoding maps comprising an array mapping each of the pair to a corresponding Huffman prefix code; and encoding at least one of the plurality of numbers using the one or more encoding maps.

Abstract: The present invention relates to a multiple-dimension-data-organization method. More specifically, this method uses an n-dimensional cube (M-cube) in which each face displays the data on a 2-D planar surface and in which the x and y axes may be changed in accordance with the user's request. More specifically still, the data to be viewed may be easily changed by the user by means of a simple rotation command using a touch-sensitive interface.
