Image matching is a critical task in computer vision research, focusing on aligning two or more images with similar features. Feature detection and description constitute the core of image matching. Handcrafted detectors are capable of obtaining distinctive points but these points may not be repeatable on the image pairs especially those with dramatic appearance changes. On the contrary, the learned

Domain generalization (DG) aims to solve the problem of significant performance degradation when target domain data collected from the Out-Of-Distribution (O.O.D). Previous efforts try to exploit invariant features in the source domain through CNN networks. However, inspired by causal mechanisms, we find that the complex spurious-invariant information is still hidden in this view invariant features

Currently, the research on cross-scene classification of hyperspectral image (HSI) based on domain generalization (DG) has received wider attention. The majority of the existing methods achieve cross-scene classification of HSI via data manipulation that generates more feature-rich samples. The insufficient mining of complex features of HSIs in these methods leads to limiting the effectiveness of the

Point cloud compression is critical for the success of immersive multimedia applications. For attribute compression in geometric point cloud compression (G-PCC), Region Adaptive Hierarchical Transform (RAHT) is the preferred coding method. This paper presents several advances to predictive coding with RAHT: i) Sample Domain Prediction: Prediction in RAHT is done in transform domain. This introduces
