Image denoise based on Curvelet transform
Qiaoling Yi, Yu Weng, Jiayong He · 2014
The Curvelet transform is a new transform for image processing which has being developed for last years. It makes the line as a basic cell for transforming, so it is able to represent smooth and edge parts of image with sparsity. Curvelet transform can provide stable, efficient, and near-optimal representation of otherwise smooth objects discontinuities along smooth curves. It is a multiscale transform which is more adapt to the image processing after wavelet transform.
