TL;DR: Weighted v-spline curves are used here with a new technique that forms a parametric surface interpolant to a given rectangular set of control points that can be interactively changed by manipulating the control points or by modifying the interval or point tension parameters.

TL;DR: The results indicate that the proposed interpolation method does not only outperform the existing method in terms of objective and subjective image quality but also requires less complexity.
Abstract: In this paper, an image interpolation method based on even-odd decomposition (EOD) is proposed. An input signal for interpolation is decomposed to even and odd vectors by EOD. And then different interpolation methods are applied to even and odd vectors, respectively. This paper presents an analysis on the two vectors and new design methods for them. Also, based on the new design method, a signal flow graph of the proposed method is provided and compared with the CCI method in terms of complexity. To evaluate the proposed method, we conduct experiments and complexity comparison. The results indicate that the proposed interpolation method does not only outperform the existing method in terms of objective and subjective image quality but also requires less complexity.

TL;DR: In this paper, the cubic spline interpolation method is used for kinetic data analysis, and its application to experimental data is demonstrated and its performance is quantitatively compared with better known but less accurate methods.
Abstract: The differential method of van't Hoff is a powerful method for kinetic data analysis if accurate rates of reaction can be found. Differentiation methods reported in the literature are inadequate, particularly when applied to data which is unequally spaced or which is subject to random error. A need is therefore expressed for a general numerical method of differentiation which can be readily applied in kinetic analysis. This paper suggests the use of the cubic spline, an interpolation method which overcomes the difficulties of other methods and gives exceptionally accurate derivatives. The theory of the cubic spline, its properties, and uses are discussed. Its application to experimental data is demonstrated and its performance is quantitatively compared with better known but less accurate methods.

TL;DR: Computer simulation results at 2:1 subsampling rate of the proposed local motion-adaptive interpolation techniques combined with the conventional three-step search algorithm and the fast BMA using integral projections are given.
Abstract: Interpolation techniques based on block-by-block motion compensation algorithms are studied for the video conference/video telephone signals. In this paper, we propose the local motion-adaptive interpolation technique, which can be used in the codec using a motion compensated coding-block matching algorithm (MCC-BMA). Computer simulation results at 2:1 subsampling rate of the proposed local motion-adaptive interpolation techniques combined with the conventional three-step search algorithm and the fast BMA using integral projections are given.
