C1 bicubic splines over general T-meshes

The present authors have introduced polynomial splines over T-meshes (PHT-splines) and provided the theories and applications for PHT-splines over hierarchical T-meshes. This paper generalizes PHT-splines to arbitrary topology over general T-meshes with any structures. The general PHT-spline surfaces can be constructed through an unified scheme to interpolate the local geometric information at ...

High Accuracy Bicubic Interpolation Using Image Local Features

In this paper, we propose a novel bicubic method for digital image interpolation. Since the conventional bicubic method does not consider image local features, the interpolated images obtained by the conventional bicubic method often have a blurring problem. In this paper, the proposed bicubic method adopts both the local asymmetry features and the local gradient features of an image in the int...

Image Resolution Enhancement Using Bicubic and Spline Interpolation Techniques

Resolution enhancement (RE) schemes (which are not based on wavelets) suffer from the drawback of losing high-frequency contents (which results in blurring). The discrete-wavelettransform-based (DWT) RE scheme generates artifacts (due to a DWT shift-variant property). A wavelet-domain approach based on dual-tree complex wavelet transform (DT-CWT) and nonlocal means (NLM) for RE of the satellite...

Effect of Bicubic Image Interpolation on Retinal Vascular Caliber Measurement

Aim: To assess whether retinal vascular caliber measurement from digital fundus photographs using IVAN software (University of Wisconsin, Madison, WI) is affected by bicubic image interpolation using image processing software (Photoshop version 5.5, Adobe Systems Inc., San Jose, CA). Material and methods: 32 good quality optic disc centered retina photos (slides) acquired in healthy volunteers ...

Range Restricted Interpolation Using Cubic Bezier Triangles

A range restricted C interpolation local scheme to scattered data is derived. Each macro triangle of the triangulated domain is split into three mini triangles and the interpolating surface on each mini triangle is a cubic Bézier triangle. Sufficient conditions derived for the non-negativity of these cubic Bézier triangles are expressed as lower bounds to the Bézier ordinates. The non-negativit...
