Professors Tinku Acharya & Ping-Sing Tsai
Professors Tinku Acharya (Avisere Inc and Arizona State University) and Ping-Sing Tsai (University of Texas, Pan American) explain that interpolation algorithms can be grouped into two categories, adaptive or non-adaptive "The computational logic of an adaptive image interpolation technique is mostly dependent upon the intrinsic image features and contents of the input image whereas computational logic of a non-adaptive image interpolation technique is fixed irrespective of the input image features". They discuss the progress of both non-adaptive and adaptive image interpolation techniques, propose a new algorithm for image interpolation in a discrete wavelet transform domain, describe the underlying computational foundations of all these algorithms and their implementation techniques, and show the impact of these algorithms in terms of image quality metrics and computational requirements for implementation.
