23515 单幅图像盲去卷积的目的是从一幅观测的模糊图像估计出模糊核和清晰图像。 The purpose of single image blind deconvolution is to estimate the unknown blur kernel from a single observed blurred image and recover the original sharp image.
23516 该问题是严重病态的，尤其是观测图像中噪声不可忽略时更具挑战性。 Such a task is severely ill-posed and even more challenging especially in the condition that the noise in the input image can not be negligible.
23517 该文主要针对如何有效利用低秩先验约束进行噪声模糊图像盲去卷积问题，提出一种在交替最大后验(MAP)估计框架下利用低秩先验约束的单幅噪声模糊图像盲去卷积方法。 In this paper, the main problem this study focuses on is how to effectively apply low rank prior to blind deconvolution. A single noisy and blurry image blind deconvolution algorithm is proposed, using alternating Maximum A Posteriori (MAP) estimation combined with low rank prior.
23518 首先，在估计中间复原图像时，利用低秩先验约束对复原图像中的噪声进行抑制。 First, when estimating the intermediate latent image, low rank prior is used as the constraint that is used for noise suppression of the restored image.
23519 然后，采用降噪后的中间复原图像估计模糊核，得到更好质量的模糊核估计。 Then the denoised intermediate latent image in turn leads to higher quality blur kernel estimation.
23520 迭代上述两个操作获得最终可靠的模糊核估计。 These two operations are iterated in this manner to arrive at reliable blur kernel estimation.
23521 最后，根据所估计的模糊核，通过非盲去卷积方法复原出清晰图像。 Finally, the non-blind deconvolution method is chosen to be used with sparse prior knowledge to achieve the final latent image restoration.
23522 实验结果表明：所提方法在定量和定性评价指标上优于已有的代表性方法。 Extensive experiments manifest the superiority of the proposed method over state-of-the-art techniques, both qualitatively and quantitatively.

23524 其中 L 波段 1 维综合孔径辐射计是 MICAP 的核心，用以实现海洋盐度高精度观测。 The L band one dimensional synthetic aperture radiometer is a key part of MICAP, which is used to realize the high precision measurement of the ocean salinity.
