【摘要】：在實際應(yīng)用中,噪聲不可避免,因此,圖像去噪一直是圖像處理領(lǐng)域研究的重點,并且近年來受到越來越多的研究者的青睞。該文首先基于Meridian分布和全變分(Total Variational,TV)的統(tǒng)計特性,提出一種全變分模型來復(fù)原alpha穩(wěn)態(tài)噪聲環(huán)境下的含噪聲圖像。此外,為了保證模型解的唯一性,對提出的全變分模型添加了一個二次懲罰項,得到一個嚴格凸的全變分模型,然后,使用原始-對偶算法對提出的全變分模型進行求解,并證明了該算法的收斂性。最后,進行了仿真實驗,并對實驗結(jié)果進行了分析,實驗結(jié)果驗證了提出模型的可行性與有效性。
[Abstract]:In practical application, noise is inevitable, so image denoising has been the focus of image processing research, and has been more and more popular in recent years. Based on the statistical properties of Meridian distribution and Total Variational TVs, a total variational model is proposed to restore noisy images in alpha stationary noise environment. In addition, in order to ensure the uniqueness of the solution of the model, a quadratic penalty term is added to the proposed total variational model, and a strictly convex total variational model is obtained. Then, the primal-dual algorithm is used to solve the proposed total variational model. The convergence of the algorithm is proved. Finally, the simulation experiment is carried out, and the experimental results are analyzed. The experimental results verify the feasibility and validity of the proposed model.
