Abstract
Discrete cosine transform (DCT) coding is widely used for compression of rectangularly sampled images. We address efficient DCT coding of nonrectangularly sampled images. To this effect, we discuss an efficient method for the computation of the DCT on nonrectangular sampling grids using the Smith-normal decomposition. Simulation results are provided.<>
