Spatial-temporal method for image denoising based on BLS-GSM in Curvelet transformation

We propose an image sequences (video) denoising method based on image temporal-spatial GSM (Gaussian Mixture Scales) modeling in Curvelet transformation. Firstly, we construct the Bayesian Least Squared GSM (BLS-GSM) based image denoising model from single image and obtain the optimal coefficient es...
