    Abstract: A method for optimizing migration efficiency of a data file over network is provided. Specifically, a total time of compression time of the data file, transfer time of the data file over the network, and decompression time of the data file, is minimized by adaptively selecting compression methods to compress each data block of the data file. For selecting a compression method for a data block, information entropy of the data block is analyzed, and a real status of computing and system resources is considered. Further, trade-off among the resource usage, compassion speed and compression ratio is made to calculate an optimized transmission solution over the network for each data block of the data file.

    Abstract: The invention discloses a method and device for automatically converting a sign and a method for automatically reading a sign. The method for automatically converting a sign comprises: disposing a first number of modules dispersedly within the sign, the first number being equal to a number of modules of a two-dimensional code that denote the sign; determining a mapping relation between the first number of modules and the respective modules of the two-dimensional code; and setting the first number of modules respectively to have same properties as the respective modules to which they are mapped of the two-dimensional code, so as to generate a converted sign. With the above method and device for automatically converting a sign, various signs can be automatically converted to machine readable signs, so that people and machines can easily understand these signs.
