The implementation of 2-dimensional (2-D) linear transformations (e.g., Fourier and cosine transforms) is a computationally intensive task. In progressive image processing, it is desirable to use algorithms that produce outputs of 2-D transformations in successive steps throughout the computations. We propose an example of these algorithms for successive inversion of discrete cosine transformed images. The approach is suitable for interactive applications of progressive image presentation.
