A Method for High Resolution Color Image Zooming using Curvature Interpolation
نویسنده
چکیده
We introduce a new zooming algorithm curvature interpolation method(CIM) based on partial differential equation, which produce high resolution(HR) color image by solving a linearized curvature equation. Partial Differential Equations (PDEs) have become an important tool for interpolation methods in image processing and analysis. CIM first evaluates the curvature of the low-resolution image, after interpolating the curvature to the high-resolution image domain, to minimize the artifacts such as image blur and the checkerboard effect. The results demonstrate that our new CIM algorithm significantly enhances the quality of the interpolated images with sharp edges over linear interpolation methods.

A New Technique for Image Zooming Based on the Moving Least Squares
In this paper, a new method for gray-scale image and color zooming algorithm based on their local information is offered. In the proposed method, the unknown values of the new pixels on the image are computed by Moving Least Square (MLS) approximation based on both the quadratic spline and Gaussian-type weight functions. The numerical results showed that this method is more preferable to biline...
متن کاملImage Zooming using Non-linear Partial Differential Equation
The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...
متن کاملTuning Shape Parameter of Radial Basis Functions in Zooming Images using Genetic Algorithm
Image zooming is one of the current issues of image processing where maintaining the quality and structure of the zoomed image is important. To zoom an image, it is necessary that the extra pixels be placed in the data of the image. Adding the data to the image must be consistent with the texture in the image and not to create artificial blocks. In this study, the required pixels are estimated ...
متن کاملEnlargement of Image Based Upon Interpolation Techniques
For real time applications, simple linear or cubic interpolation and FCBI (Fast Curvature Based Interpolation) algorithms are applied for the task of enlargement of images without changing super resolution (low resolution and high resolution), but the results obtained are not really satisfactory, being affected by relevant artifacts like blurring and jaggies. In this paper we describe a new met...
متن کاملImage Zooming Using Radial Basis Fucntion Interpolation for Iris Recognition
Low resolution iris image can degrade the performance of iris recognition. A new iris image zooming method by using edge-directed image upsampling method based on radial basis function (RBF) interpolation [9] is proposed to restore a single iris image into a highresolution image. By increasing the resolution of iris image, we found that the performance of iris recognition was increased.
