Structure-preserving interpolation of bilinear control systems [PDF]
Advances in Computational Mathematics, 2021 AbstractIn this paper, we extendthe structure-preserving interpolatory model reduction framework, originally developed for linear systems, to structured bilinear control systems. Specifically, we give explicit construction formulae for the model reduction bases to satisfy different types of interpolation conditions. First, we establish the analysis for

Effects of rescaling bilinear interpolant on image interpolation quality [PDF]
Optoelectronic Imaging and Multimedia Technology V, 2018 Rescaling bilinear (RB) interpolant’s pixels is a novel image interpolation scheme. In the current study, we investigate the effects on the quality of interpolated images. RB determines the lower and upper bounds using the standard deviation of the four nearest pixels to find the new interval or range that will be used to rescale the bilinear ...

Interpolation with bilinear differential forms [PDF]
Proceedings of the 44th IEEE Conference on Decision and Control, 2006 We present a recursive algorithm for modeling with bilinear differential forms. We discuss applications of this algorithm for interpolation with symmetric bivariate polynominals, and for computing storage functions for autonomous systems.

Implementing bilinear interpolation with quantum images [PDF]
Digital Signal Processing, 2021 Abstract A bilinear interpolation technique is proposed for flexible representations of quantum images (FRQIs). In this process, several quantum modules were developed, including assignment, increment, and quarter modules, for use in an interpolation circuit. The network structure of these circuits, capable of both up-sampling and down-sampling FRQIs,

Hardware acceleration of number theoretic transform for zk‐SNARK
Engineering Reports, EarlyView., 2023 An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Image Enlargement by Applying Coordinate Rotation and Kernel Stretching to Interpolation Kernels
EURASIP Journal on Advances in Signal Processing, 2010 Conventional image interpolation methods such as the bilinear and bicubic algorithms determine the weights of the reference pixels based on the special distance between the supplementary pixel and the reference pixels. They suffer from some problems such

Enhanced spatial error concealment with directional entropy based interpolation switching [PDF]
, 2006 This paper describes a spatial error concealment method that uses edge related information for concealing missing macroblocks in a way that not only preserves existing edges but also avoids introducing new strong ones.

Implementation of 3D HRTF Interpolation in Synthesizing Virtual 3D Moving Sound
International Journal of Technology, 2017 3D sound is a new trend in various media, such as movies, video games, and musicals. Interpolated head-related transfer functions (HRTFs) are a key factor in its production, due to real-time system limitations in storing measured HRTFs.
