Bi-Cubic Interpolation Algorithm Based on Non-Subsampled Contourlet Transformation

Article Preview

Abstract:

This article introduces several interpolation algorithms, and analyze the characteristic and disadvantage of wavelet transformation and contourlet transformation. A Bi-cubic interpolation algorithm based on non-subsampled contourlet transformation is described. The experiments prove this algorithm can improve the quality of image reconstruction better than Bi-cubic interpolation, wavelet bi-cubic interpolation and contourlet interpolation.
