An edge-directed bicubic interpolation algorithm

2010 3rd International Congress on Image and Signal Processing, 2010
Image interpolation is a technique of producing a highresolution image from its low-resolution counterpart, which is often required in many image processing tasks. In this paper, we propose an edge-directed bicubic convolution (BC) interpolation. The proposed method can well adapt to the varying edge structures of images.

High Accuracy Bicubic Interpolation Using Image Local Features

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2007
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.

BICUBIC SPLINE INTERPOLATION: A QUANTITATIVE TEST OF ACCURACY AND EFFICIENCY*

Geophysical Prospecting, 1979
AbstractTwo different methods for the construction of an approximation to bicubic splines for interpolating irregularly spaced two‐dimensional data are described. These are referred to as the least squares line (LSL) and linear segment (LINSEG) construction procedures.A quantitative test is devised for investigating the absolute accuracy and efficiency

Alternatives to Bicubic Interpolation Considering FPGA Hardware Resource Consumption

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2021
Bicubic interpolation is widely used in real-time image processing systems because of its quality. The real-time implementation of bicubic interpolation requires a lot of hardware resources, especially the number of multipliers because it represents high computational complexity.

Bi Histogram Equalization Based Image Enhancement with Bicubic Interpolation

ECS Transactions, 2022
In image processing, enhancement histogram equalization is the widely used technique for contrast enhancement. However, this technique tends to change the brightness of the image. Here, the contrast and resolution of image were enhanced using the proposed Bi Histogram Equalization Based Image Enhancement with Bicubic Interpolation (BHBI) technique.

Curvilinear Bicubic Spline Fit Interpolation Scheme

Optica Acta: International Journal of Optics, 1973
Modification of the rectangular bicubic spline fit interpolation scheme so as to make it suitable for use with a polar grid pattern. In the proposed modified scheme the interpolation function is expressed in terms of the radial length and the arc length, and the shape of the patch, which is a wedge or a truncated wedge, is taken into account ...

Bicubic Interpolation Based Audio Authentication (BIAA)

2017
Authenticating audio songs/signals is one of the challenging issues in the domain of audio processing and analysis. Different techniques like embedding secret code in amplitude or frequency components, harmonics alternation, embedding audio/image, etc. are frequently used by the researchers for audio signal authentication.

Efficient super-resolution algorithm using overlapping bicubic interpolation

2017 IEEE 6th Global Conference on Consumer Electronics (GCCE), 2017
In practical CCTV applications, there are problems of the camera with low resolution, camera fields of view, and lighting environments. These could degrade the image quality and it is difficult to extract useful information for further processing. Super-resolution techniques have been proposed widely by the researchers.

Bumpless monotonic bicubic interpolation for MOSFET device modelling

IEE Proceedings I Solid State and Electron Devices, 1985
A bumpless monotonic bicubic interpolation (MBI) technique is proposed. The method is applied to MOSFET device modelling for guessing at a very smooth interpolated curved surface. Monotonic increase in a two-dimensional surface can be held, even if the actual device characteristics show steepest change, like punchthrough characteristics.

Weighted bicubic spline interpolation to rapidly varying data

ACM Transactions on Graphics, 1987
The weighted bicubic spline that is a C 1 piecewise bicubic interpolant to three-dimensional gridded data is introduced. This is a generalization of the univariate weighted spline, developed by Salkauskas, in that a weighted minimization problem is solved. The minimization problem solved is a weighted version of the
