Curvelets remain coherent waveforms under the action of the wave equation in a smooth medium. More information can be found in the papers. By releasing the CurveLab toolbox, we hope to encourage the dissemination of curvelets to image processing, inverse problems, and scientific computing.
Curvelets were introduced in 1999 by Candès and Donoho to address the edge representation problem. The definition they gave was based on windowed ridgelets. In 2002, they simplified the definition of curvelets and constructed a new tight frame. Curvelets were introduced in 1999 by Candès and Donoho to address the edge representation problem.
Curvelets are multiscale, oriented, non-adaptive representations of images and multi-dimensional signals. If some of these words didn’t make sense, you’re in the right place.
Curvelets A curvelet frame f' g is a wave packet frame on L2(R 2) based on second dyadic decomposition. (x) f = X ' (x)
