7. Conclusion
A digital implementation of the curvelet transform was proposed and applied on two
images: a synthetic image (where the distribution of the noise is known) and a real image
(where the distribution of the noise is not known). The resuits are promising on both the
synthetic image and the real image. They show significant reduction of the noise while
preserving the edges of the image.
While the results are promising there is much work to be done. In the denoising scheme
the threshold is chosen with ad hoc methods. A great improvement would be made by
finding some criteria for choosing this threshold.
