Abstract: A method executed by a computer system that transmits a multimedia content through a negative-base number. The method includes generating a binary sequence for the multimedia content, converting the binary sequence into a negative-base number, receiving the negative-base number, retrieving a negative base of the negative base number, calculating the binary sequence based on the negative-base number and the negative base, and obtaining the multimedia content based on the binary sequence.

Abstract: A method constructs an image with improved peak signal-to-noise ratio (PSNR) from a scattered pixel set. The method generates an approximation function that is a linear combination of a plurality of Many-Knot (MK) spline basis functions, and constructs the image with improved PSNR by conducting a least squares treatment on the approximation function to minimize a residual of each pixel value in the scattered pixel set from the approximation function.

Abstract: Example embodiments include a method that reduces consumption of computer resources in a computer system to reconstruct a shape of a multi-object image using finite terms. The method includes computing an initial function by performing V-system of degree 0 and functions of curves by performing hierarchical V-system. Norms of the functions of curves are compared with a predetermined threshold. A reconstruction function of the shape of the multi-object image is generated by summing the initial function and the functions of curves.

Abstract: A method for coding data includes: representing a first data in digital form as digital information; transforming the digital information into a first Gaussian integer; determining a relationship between the first Gaussian integer and a second Gaussian integer; and deriving, based on the determined relationship, a key for converting between the first Gaussian integer and the second Gaussian integer so as to associate the first data with a second data represented by the second Gaussian integer. The present invention also provides a system and a non-transient computer readable medium for implementing the method.
