Directional Bicubic Interpolation — A New Method of Image Super-Resolution [PDF]
Advances in Intelligent Systems Research, 2013 Bicubic interpolation is a standard method in image interpolation field because of its low complexity and relatively good results. But as it only interpolates in horizontal and vertical directions, edges easily suffer from artifacts such as blocking, blurring and ringing.

Single image super resolution based on multi-scale structure and non-local smoothing
EURASIP Journal on Image and Video Processing, 2021 In this paper, we propose a hybrid super-resolution method by combining global and local dictionary training in the sparse domain. In order to present and differentiate the feature mapping in different scales, a global dictionary set is trained in ...

Linear Methods for Image Interpolation
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 ...

Comparison of interpolation methods for raster images scaling [PDF]
Научно-технический вестник Брянского государственного университета, 2017 The article is devoted to the problem of efficient scaling of raster images. We consider some negative effects, related with scaling of raster images. Besides, we consider an analysis of several methods that are used to increase sizes of ras-ter images ...

Spurious PIV Vector Correction Using Linear Stochastic Estimation
Fluids, 2019 Techniques for the experimental determination of velocity fields such as particle image velocimetry (PIV) can often be hampered by spurious vectors or sparse regions of measurement which may occur due to a number of reasons.
