Linear Methods for Image Interpolation

open access: yesImage 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 ...

Error concealment using motion field interpolation [PDF]

open access: yes, 1998
In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear

Real Interpolation of Compact Bilinear Operators

open access: yesJournal of Fourier Analysis and Applications, 2017
We establish an analog for bilinear operators of the compactness interpolation result for bounded linear operators proved by Cwikel and Cobos, Kühn and Schonbek. We work with the assumption that : (A0+ A1)×(B0+ B1) −→ E0+E1 is bounded, but we also study the case when this does not hold. Applications are given to compactness of convolution operators and

Interpolation Filter Design Based on All-Phase DST and Its Application to Image Demosaicking

open access: yesInformation, 2018
Based on a deep understanding of all-phase digital filter (APDF) design and all-phase biorthogonal transform (APBT), this paper will further study the windowed all-phase digital filter (WAPDF) and windowed all-phase biorthogonal transform (WAPBT ...

Multivariate moment-matching for model order reduction of quadratic-bilinear systems using error bounds

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
We propose an adaptive moment-matching framework for model order reduction of quadratic-bilinear systems. In this framework, an important issue is the selection of those shift frequencies where moment-matching is to be achieved.

Analysis of Interpolation Methods in the Validation of Backscattering Coefficient Products

open access: yesSensors, 2023
Validation is the basis of synthetic aperture radar (SAR) image quantification applications. Based on the point target of the field site, the radiation characteristics of the backscattering coefficient image can be used to optimize the SAR imaging, and ...

Colour Restoration of Image Obtained from CCD Sensor Directly

open access: yesCybernetics and Information Technologies, 2014
The original image data obtained from Charge-coupled Device (CCD) can be called original data, which is lack of color information. In order to restore the color of original image, firstly, we design a Bayer color filter array, and then we use bilinear ...

INDEX QUALITY ASSESMENT CITRA TERINTERPOLASI (SSIM dan FSIM)

open access: yesJUTEI (Jurnal Terapan Teknologi Informasi), 2017
Ada sejumlah aplikasi dalam pengenalan pola yang membutuhkan citra dengan ukuran tertentu. Ukuran citra menentukan hasil dari pengenalan pola suatu sistem. Suatu metode interpolasi digunakan untuk menyesuaikan ukuran suatu citra.

A Line Integral Convolution Method With Dynamically Determining Step Size and Interpolation Mode for Vector Field Visualization

open access: yesIEEE Access, 2019
The line integral convolution method can obtain a continuous and dense vector streamline texture. The traditional fixed step size gets larger texture noise, while the exact calculation step method (such as the Runge-Kutta method) is time-consuming.
