Non-Convex High-Order TV and ℓ 0 -Norm Wavelet Frame-Based Speckle Noise Reduction

To obtain natural restorations from the noisy images contaminated by speckle noise, this brief presents a novel hybrid non-convex regularizers model for image denoising. The proposed new variational model closely combines the superiorities of non-convex high-order total variation function and [Formu...
