Abstract
In this paper, we present a review of some commonly used methods for signal interpolation and/or estimation, from a set of randomly chosen samples. Most of these methods were originally devised for 1D signals. First we extend these methods to 2D and then perform a comparative study. Our experimental results show good interpolation/reconstruction performances of some methods for sampling ratios as small as 5% of the original number of pixels.
