Image restoration via Bayesian dictionary learning with nonlocal structured beta process.
Journal of Visual Communication and Image Representation(2018)
摘要
•Nonlocal structured beta process is proposed to exploit the structure prior.•Does not depend on noise variance and robust due to non-parametric property.•The performance of image denoising and inpainting are improved.
