Signal Processing Issues in Synthetic Aperture Radar and Computer Tomography
Other work dealt with bandlimited signal interpolation. These studies involved designing a new interpolation algorithm, which is minimax optimal for the interpolation of bandlimited signals. Assuming a class of computationally efficient interpolators, a suboptimal interpolation algorithm was …

Patient-specific technology for in vivo assessment of 3-D spinal motion
… evaluating the accuracy of 3-D kinematic interpolation techniques in reconstructing spinal kinematic data in order to reduce radiation exposure from bi-planar fluoroscopic diagnostic techniques. Several interpolation and sampling algorithms were evaluated in reconstructing cadaveric lumbar …

The resolution enhancements of real-time captured images
… ways. First, an improved color filter array interpolation algorithm is proposed, which offers high accuracy with reasonable performance. Second, the thesis discusses a mechanism in which real-time user feedback is given to aid in the capture and creation of mosaic images. Lastly, the …

Innovative color management methods for RGB printing
… input and output colors obtained via a B-spline interpolation algorithm. The rendered image is re-introduced into the print stream for final printing. The prototype achieved successful results and can be packaged with commercial printers after a few refinements.

NeVR: Learning Continuous Neural Video Representation with Local Feature Codes for Video Interpolation
<p>Video frame interpolation aims to synthesis a non-exists intermediate frame guided by two successive frames. Recently, some work shows excellent results in learning continuous representation of temporally-varying 3D objects with neural field (NF), which could be used for interpolating the …

Parametrized maneuvers for autonomous vehicles
… admissible vehicle motions. A trajectory interpolation algorithm uses projection and integration methods to create the classes, starting from arbitrary user-provided maneuver examples, including those obtained from standard nonlinear optimization or motion capture of human-piloted vehicle …

A Study of Earth Radiation Budget Radiometric Channel Performance and Data Interpretation Protocols
… used to compensate for unsampled data. The time interpolation algorithm applied to a limited number of observations can produce significantly biased estimates of monthly mean fluxes. A diurnal interpolation protocol using correlative ISCCP cloudiness data is developed to compensate for sparse …

Image interpolation and denoising in discrete wavelet transform domain
… the textures of an image after denoising. A new algorithm is proposed in this thesis for image denoising in the DWT domain with no blurring effect. This algorithm uses a suite of feature extraction and image segmentation techniques to construct filter masks for denoising. The novelty of the …

Intelligent Side Information Generation in Distributed Video Coding
… been based on linear motion compensated temporal interpolation (LMCTI), though these do not always produce satisfactory SI quality, especially in sequences exhibiting non-linear motion. This thesis presents an intelligent higher order piecewise trajectory temporal interpolation (HOPTTI) framework …

Point-based mathematics for computer-aided manufacture
… by the use of some unspecified high quality interpolation algorithm. This is in contrast to the conventional CAD/CAM approach where explicit parametric expressions are used to describe the part. The research is founded on the Inverse Offset Method (IOM) proposed by Kishinami; the algorithm is …

Lagrangian studies of turbulent mixing in a vessel agitated by a rushron turbine: positron emission particle tracking (PEPT) and computational fluid dynamics (CFD)
… in the impeller region. By using a selective interpolation algorithm of the tracer locations, this problem was greatly reduced although a perfect match with optical technique is not feasible. As further contribution to Lagrangian studies of mixing processes, Computational Fluid Dynamics (CFD) …

40 Years Global Estimation of Aerosol Optical Depth Profiles Using MISR and TOMS Aerosol Products
… These data gaps were filled using appropriate interpolation algorithms. Synthetic gaps were created in the locations containing original data and filled using the interpolation algorithm. Uncertainty values were calculated as the difference between the original data and the interpolated data. …

FDTD subgridding with higher order derivative approximations
… focus on the implementation of a new subgridding algorithm designed to simplify the complexities that arise with high frequency designs. This new FDTD subgridding algorithm will be instrumental in the reduction of memory usage and execution time for applications such as antennas, antenna arrays …

Accelerator-based look-up table for coarse-grained molecular dynamics computations
… atomistic simulation. While coarse-graining algorithmically reduces the total number of particles in consideration, the execution time and efficiency scales poorly for large systems. Both fully-atomistic and coarse-grained developers have accelerated packages using high-performance parallel …

Modeling of Polar Cap Ionospheric Patches and Attendant Plasma Instabilities: Initialization from Data and Parametric Analysis
<p>There is a robust history of theoretical work on ionospheric plasma patches and their attendant plasma fluid irregularities, particularly within the polar cap region. Within this region though, plasma theory does not always yield tractable problems with succinct analytic solutions that are …
