ABSTRACT
In this paper we proposed fast and accurate interpolation and resizing of images using lifting schemeapproach. 5/3 lifting scheme is an accurate and computationally inexpensive interpolation technique forimage resizing. We compared the bilinear interpolation, Haar lifting scheme and 5/3 lifting scheme in thispaper. The lifting scheme algorithm is applied for image interpolation to resize the image. In case ofreduction in size, the image components are reduced and the reconstruction will be carried out to theoriginal image. The reconstruction results are better by using Mean Squared Error (MSE) and Peak Signalto Noise Ratio (PSNR) with other techniques like bilinear interpolation and Haar lifting schemes. Theinterpolation and reconstruction is executed in much less time with better MSE and PSNR as compared toBilinear and Haar lifting schemes.
