In mathematics, bicubic interpolation is an extension of cubic interpolation for interpolating data points on a two dimensional regular grid. The interpolated surface is smoother than corresponding surfaces obtained by bilinear interpolation or nearest-neighbor interpolation. Bicubic interpolation can be accomplished using either Lagrange polynomials, cubic splines, or cubic convolution algorithm.
In image processing, bicubic interpolation is often chosen over bilinear interpolation or nearest neighbor in image resampling, when speed is not an ....etc

Survey of Matrix Multiplication Algorithms

Abstract
Matrix multiplication is one of the most fundamental operations in linear algebra and serves as the main building block in many different algorithms, including the solution of systems of linear equations, matrix inversion, evaluation of the matrix determinant, in signal processing, and the transitive closure of a graph. In several cases the asymptotic complexiti ....etc

Abstract

When two or more images are spliced together, to create high quality and consistent image forgeries, almost always geometric transformations such as scaling or rotation are needed. These procedures are typically based on a resampling and interpolation step. In this paper, we introduce a blind method capable of finding traces of resampling and interpolation. Unfortunately, the proposed method, as well as other existing interpolation/resampling detectors, is very sensitive to noise. The noise degradation causes that detectable ....etc

ABSTRACT
An immeasurable amount of multimedia information is available today in digital archives, on the Web, in broadcast data streams, and in personal and professional databases and this amount continues to grow. Yet, the value of that information depends on how easily we can manage, find, retrieve, access, and filter it. The transition between two millennia abounds with new ways to pr ....etc

Towards Optimal Color Image Coding using Demosaicing
Abstract We introduce an optimal approach to color image compression using demosaicing. Accordingly, we propose an efficient algorithm for color image coding. In the encoder, a
mosaic of the primary colors is encoded instead of the full color image. This mosaic is considered as four different color channels that are compressed using subband transform coders. In the decoder, a demosaicing algorithm is applied to the decompressed channels to reconstruct the ....etc

GRAPHICS PROCESSING UNIT
(GPU)
ABSTRACT
A Graphics Processing Unit (GPU) is a microprocessor that has been designed specifically for the processing of 3D graphics. The processor is built with integrated transform, lighting, triangle setup/clipping, and rendering engines, capable of handling millions of math-intensive processes per second. GPUs allow products such as desktop PCs, portable computers, and game consoles to process real-time 3D graphics that only a few years ago were only available on high-end workstations. Used primarily for 3- ....etc

Resizing image using bilinear interpolation algorithm in MATLAB



INTRODUCTION
Our project is titled Resizing image by using bilinear interpolation algorithm in MATLAB. In this project we used some principle elements to create MATLAB Graphical User Interface. We choose this project because we faced some problems when we tried to resize images by some other programs. The problem faced was losing of pixels in the original image, thereby degrading the picture quality.
The main ....etc

Abstract
In this paper, we propose a method of image resolution enhancement using a single image. The proposed method enhances the resolution by emphasizing the high frequency of a magnified low resolution image. Experimental results show that the performance of our method has been improved by 13%-25% over the conventional interpolation methods.
I. INTRODUCTION
Recently, many users require high resolution images as applications and demands for high quality images are increasing. Moreover, we often transfer images by using mob ....etc
