摘要：Scaling operation plays an important role in resizing digital images. Scaling is used to perform shrinking (subsampling) and zooming (oversampling) on digital images. Zooming implies enlargement or magnification of an image for better view. Theoretically, the paper presents broad categorization and comparison of image zooming techniques. Various techniques range from traditional pixel replication, interpolation and advanced techniques based on fuzzy logic. A combination of fuzzy and interpolation gives best results. From implementation point of view PSNR and SSIM are used to compare the performance of these techniques.
