Curvelet is a kind of multi-scale transform

it provides a expression of stability

efficient and optimal

for target function with smooth-curve-singularity.A coefficients product image denoising method based on second generation curvelet is proposed

using coefficients of decomposition has the same characteristics in different scales

based on second generation curvelet.The result shows that the algorithm achieves better denoising than wavelet transform and simple thresholding methods.
