In this paper, the fundamental concepts of interpolation and its applications are discussed. The four interpolation algorithms such as Nearest Neighbor Replacement (NNR) Interpolation, Bi-Cubic (BC) Interpolation, Wavelet Transformation-based (WT) Interpolation and Edge Sensitive (ES) Interpolation are examined and compared based on quality and accuracy. The performance of the interpolation algorithm was analyzed by means of PSNR (Peak Signal to Noise Ratio) and FOM (Figure of Merit).
