Image Interpolation Using 5/3 Lifting Scheme Approach
P. Ashok Babu, K. Venkata Prasad · Signal & Image Processing An International Journal · 2011
In this paper we proposed fast and accurate interpolation and resizing of images using lifting scheme approach.5/3 lifting scheme is an accurate and computationally inexpensive interpolation technique for image resizing.We compared the bilinear interpolation, Haar lifting scheme and 5/3 lifting scheme in this paper.The lifting scheme algorithm is applied for image interpolation to resize the image.In case of reduction in size, the image components are reduced and the reconstruction will be carried out to the original image.The reconstruction results are better by using Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR) with other techniques like bilinear interpolation and Haar lifting schemes.The interpolation and reconstruction is executed in much less time with better MSE and PSNR as compared to Bilinear and Haar lifting schemes.
