Multi-view clustering of remote sensing data plays a vital role in Earth observation analysis. Recently, deep graph clustering methods based on contrastive learning have significantly improved feature representation capabilities. However, most existing approaches treat all views equally, neglecting the inherent uniqueness and heterogeneity across views, which often results in two major issues: 1) discriminative features from clustering-friendly views are underexplored; and 2) redundant or noisy information from less informative views can degrade the shared representation. To address these challenges, we propose a novel multi-view graph clustering framework termed CF-MVGC for remote sensing data, which dynamically preserves discriminative features and suppresses redundancy by assessing view affinity. Specifically, we employ a dual-stage representation learning strategy to extract both view-specific discriminative features and cross-view consistent representations. To further exploit and adaptively integrate complementary information across views, we design a progressive feature filtering model that dynamically evaluates view affinity using two novel metrics, i.e., view fidelity index (VFI) and view criticality index (VCI). Based on these assessments, the module adaptively modulates feature update and reset signals, reinforcing informative views while suppressing noisy or redundant ones. Views with high affinity receive strengthened update signals to retain valuable features, while those with low affinity are subjected to enhanced reset operations to eliminate noise and redundancy. The resulting high-quality, discriminative representations lead to improved clustering performance, establishing a positive feedback loop. Experimental results on four benchmark datasets demonstrate the effectiveness and superiority of CF-MVGC against its competitors.

Multi-view clustering plays a pivotal role in remote sensing image analysis, where graph neural network-based methods have demonstrated remarkable potential by modeling data as graphs. However, existing efforts, which construct remote sensing graphs using fixed rules (e.g., K-nearest neighbors), inevitably introduce noisy edges and increase the risk of heterogeneous information diffusion, leading to inferior clustering performance. Although recent works attempt to address this issue by refining the structure, they are designed for single-view data and struggle to extend to multi-view scenarios. To bridge this gap, we propose a dual structure awareness multi-view graph clustering method named DSMVGC, which generates two distinct structures for each view through explicit and implicit perspectives. Specifically, in our method, the learning processes of structure refinement and clustering are alternately optimized to mutually enhance each other. On one hand, the explicit structure updates the topology based on inter-cluster relationships, while the implicit structure captures latent relationships not covered by the explicit structure through adversarial learning. On the other hand, the refined structures not only facilitate homogeneous message passing but also serve as prior knowledge to guide the contrastive loss, thereby enhancing the discriminability of representations for accurate clustering. Extensive experiments on five multi-view remote sensing datasets validate the effectiveness of DSMVGC.
