Gray and Color Image Contrast Enhancement by the Curvelet Transform
Contrast enhancement curvelets ridgelets wavelets
2015/6/17
We present in this paper a new method for contrast enhancement based on the curvelet transform. The curvelet transform represents edges better than wavelets, and is therefore well-suited for multiscal...
Astronomical Image Representation by the Curvelet Transform

We outline digital implementations of two newly developed multiscale representation systems, namely, the ridgelet and curvelet transforms. We apply these digital transforms to the problem of restoring...
