Bicubic spline-interpolation in polar coordinates
USSR Computational Mathematics and Mathematical Physics, 1978 Abstract THE PROBLEM of constructing a bicubic interpolation spline in a circle in polar coordinates is considered. The representation of the spline in terms of β-splines is used. The pole of the domain is excluded from the partition.

Digital Rock Core Images Super Resolution via SRCNN Based on Accelerated Bicubic Interpolation
Proceedings of the 2nd International Conference on Industrial Control Network And System Engineering Research, 2020The capability of Super Resolution Convolutional Neural Networks (SRCNN) has been proved to enhance resolution of images. We applied SRCNN to enhance digital rock core images that play an important role in analyzing rock core. In this process, we noticed

A nonlinear algorithm for monotone piecewise bicubic interpolation
Applied Mathematics and Computation, 2016We present an algorithm for monotone interpolation on a rectangular mesh.We use the sufficient conditions for monotonicity of Carlton and Fritsch.We use nonlinear techniques to approximate the partial derivatives at the grid points.We develop piecewise bicubic Hermite interpolants with these approximations.We present some numerical examples where we ...

BICUBIC SPLINE INTERPOLATION: A QUANTITATIVE TEST OF ACCURACY AND EFFICIENCY*
Geophysical Prospecting, 1979 AbstractTwo different methods for the construction of an approximation to bicubic splines for interpolating irregularly spaced two‐dimensional data are described. These are referred to as the least squares line (LSL) and linear segment (LINSEG) construction procedures.A quantitative test is devised for investigating the absolute accuracy and efficiency

An Algorithm for Monotone Piecewise Bicubic Interpolation
SIAM Journal on Numerical Analysis, 1989This paper describes an algorithm for monotone interpolation to monotone data on a rectangular mesh by piecewise bicubic functions. In [SIAM J. Numer. Anal. 22 (1985), pp. 386–400] the authors developed conditions on the Hermite derivatives that are sufficient for such a function to be monotonic.

Integer multiple quantum image scaling based on NEQR and bicubic interpolation
Chinese Physics BAs a branch of quantum image processing, quantum image scaling has been widely studied. However, most of the existing quantum image scaling algorithms are based on nearest-neighbor interpolation and bilinear interpolation, the quantum version of bicubic ...

Speedup of Bicubic Spline Interpolation
2018The paper seeks to introduce a new algorithm for computation of interpolating spline surfaces over non-uniform grids with \(C^2\) class continuity, generalizing a recently proposed approach for uniform grids originally based on a special approximation property between biquartic and bicubic polynomials.

An edge-directed bicubic interpolation algorithm
2010 3rd International Congress on Image and Signal Processing, 2010Image interpolation is a technique of producing a highresolution image from its low-resolution counterpart, which is often required in many image processing tasks. In this paper, we propose an edge-directed bicubic convolution (BC) interpolation. The proposed method can well adapt to the varying edge structures of images.
