Linear/linear rational spline interpolation
Mathematical Modelling and Analysis, 2010 For a strictly monotone function y on [a, b] we describe the construction of an interpolating linear/linear rational spline S of smoothness class C 1. We show that for the linear/linear rational splines we obtain ¦S(xi ) − y(xi )¦8 = O(h 4) on uniform ...

Linear Methods for Image Interpolation [PDF]
Image Processing On Line, 2011 We discuss linear methods for interpolation, including nearest neighbor, bilinear, bicubic, splines, and sinc interpolation. We focus on separable interpolation, so most of what is said applies to one-dimensional interpolation as well as N-dimensional ...

Linear Interpolation Revitalized [PDF]
IEEE Transactions on Image Processing, 2004 We present a simple, original method to improve piecewise-linear interpolation with uniform knots: we shift the sampling knots by a fixed amount, while enforcing the interpolation property. We determine the theoretical optimal shift that maximizes the quality of our shifted linear interpolation.

Non-linear Approximation and Interpolation Spaces
Journal of Approximation Theory, 2001 The paper studies \(n\)-term wavelet approximation in Besov and Triebel-Lizorkin spaces. In terms of interpolation spaces, the spaces of functions with prescribed degree of \(n\)-term approximation are characterized. Using these results, the author identifies the interpolation spaces between Tribel-Lizorkin and Besov spaces.

Fast Linear Interpolation [PDF]
ACM Journal on Emerging Technologies in Computing Systems, 2021 We present fast implementations of linear interpolation operators for piecewise linear functions and multi-dimensional look-up tables. These operators are common for efficient transformations in image processing and are the core operations needed for lattice models like deep lattice networks, a popular machine learning function class for interpretable,

Similarity Analysis of User Trajectories Based on Haversine Distance and Needleman Wunsch Algorithm
Elkawnie: Journal of Islamic Science and Technology, 2022 : In this paper, we discuss the similarity between two trajectories using the Needleman Wunsch algorithm. The calculation steps are interpolating the trajectory, calculating the distance between the trajectory coordinates, identifying the equivalent ...

Quadratic/linear rational spline interpolation
Mathematical Modelling and Analysis, 2013 We describe the construction of an interpolating quadratic/linear rational spline S of smoothness class C 2 for a strictly convex (or strictly concave) function y on [a, b].

A FAST MORPHING-BASED INTERPOLATION FOR MEDICAL IMAGES: APPLICATION TO CONFORMAL RADIOTHERAPY
Image Analysis and Stereology, 2011 A method is presented for fast interpolation between medical images. The method is intended for both slice and projective interpolation. It allows offline interpolation between neighboring slices in tomographic data.

Video Frame Interpolation Based on Symmetric and Asymmetric Motions
IEEE Access, 2023 Video frame interpolation is the task to synthesize intermediate frames between consecutive frames to increase the frame rate. Recently, various deep-learning techniques have been proposed to interpolate intermediate frames more reliably.
