Multi-Scale Feature Fusion

Ask about this topic

Overview

Multi-scale feature fusion studies how to combine coarse contextual information with fine spatial, temporal, or spectral details. Common approaches include feature pyramids and skip connections, attention or gated fusion, cross-scale alignment, and adaptive routing across CNN, Transformer, and state-space models. These methods are used in settings such as small-object detection, medical and remote-sensing segmentation, time-series forecasting, and multimodal perception. A central challenge is preserving useful detail while aligning scales and avoiding redundant computation, with results often depending on the task, data, and model size.
