经典基追踪模型不适用于非高斯噪声环境下的图像去噪问题。基于不同的拟舍误差项形式,提出一类新的基追踪扩展模型,并用于图像去噪。实验结果表明,本文方法在椒盐噪声环境下具有显著的去噪效果。
Considering that traditional Basis Pursuit model is not adapted to image de-nosing under non-Gaussian noise. Based on various type of fitness error, new extended Basis Pursuit model is proposed and applied into image de-nosing. Within salt-and-pepper noise image de-nosing experiments results demonstrate that the extended Basis Pursuit model can provide better de-noising results.
