论文摘要
由于其劣质特征,观察到的(嘈杂)图像的直接使用会导致分割结果差。直观地,使用无噪声图像可以有利地影响图像分割。因此,对观察到的图像和无噪声图像之间残差的准确估计是重要的任务。为此,我们详细介绍了用于图像分割的残留驱动模糊C均值(FCM),这是第一种实现准确的残差估计并导致无噪声图像以参与聚类的方法。我们通过将剩余的FCM框架集成到FCM中,提出了一个残留的FCM框架,该框架是由不同类型噪声的分布得出的残留相关的保真度项。在此框架上构建,我们通过加权混合噪声分布来提出一个加权$ \ ell_ {2} $ - norm fidelity项,从而在存在混合噪声或未知噪声的情况下导致通用残差驱动的FCM算法。此外,由于空间信息的限制,剩余估计比仅考虑观察到的图像本身的估计更可靠。进行了有关合成,医学和现实世界图像的支持实验。结果表明,所提出的算法比现有与FCM相关的算法具有较高的有效性和效率。
Due to its inferior characteristics, an observed (noisy) image's direct use gives rise to poor segmentation results. Intuitively, using its noise-free image can favorably impact image segmentation. Hence, the accurate estimation of the residual between observed and noise-free images is an important task. To do so, we elaborate on residual-driven Fuzzy C-Means (FCM) for image segmentation, which is the first approach that realizes accurate residual estimation and leads noise-free image to participate in clustering. We propose a residual-driven FCM framework by integrating into FCM a residual-related fidelity term derived from the distribution of different types of noise. Built on this framework, we present a weighted $\ell_{2}$-norm fidelity term by weighting mixed noise distribution, thus resulting in a universal residual-driven FCM algorithm in presence of mixed or unknown noise. Besides, with the constraint of spatial information, the residual estimation becomes more reliable than that only considering an observed image itself. Supporting experiments on synthetic, medical, and real-world images are conducted. The results demonstrate the superior effectiveness and efficiency of the proposed algorithm over existing FCM-related algorithms.
