Images can be represented using as locations and parameters of edges based on an edge mode. The representation was shown to be effective to reduce coding errors of images coded using SPIHT in an image postprocessing method. However, the representation results several artifacts which include "smudge and halos" artifacts and stripping artifacts. We have found the causes of these artifacts and propose a revised representation that has these artifacts significantly suppressed Also, we shall demonstrate that the revised representation can further improve the performance of the image post-processing algorithm.
