Paper Abstract

In this paper, we are discuss a multiscale analysis of discrete boundary presented by Generalized Chain Code. We briefly review the multiresolution analysis which make possible the construction of wavelets, scaling function and the associated filters. Using the discrete contour generated by Freeman Chain Code, we approximate it at several resolution levels and obtain its wavelet representation. We then reconstruct the original discrete contour from its wavelet representation also generated by Chain Code. Examples of implementation results are presented with the evaluation of entropy and signal to noise ratio to confirm the perfect visual result.
