<title>Multichannel image interpolation algorithms</title>

Abstract

In the present paper we propose a set of interpolation algorithms for improving the resolution of multichannel images, which are assumed to have a greater amount of information than a single-channel or still image. First, a multichannel interpolation algorithm on the rectangular grid is proposed. Second, a multichannel interpolation on the generalized grid for the real test image is proposed. Third, an implementationally efficient algorithm, which is suitable for real- time image processing, is also proposed based on image registration and interpolation followed by IIR filtering along the time axis. It is demonstrated that the proposed algorithms can be the theoretical bases for interpolation of dynamic image sequences, and experimental results of the proposed algorithms are also presented respectively.
