Fractal Dimension & DWRE for Detail Preservation
The core innovation lies in leveraging fractal dimension (FD) and distance-weighted regional energy (DWRE) within the curvelet domain. FD effectively captures the structural complexity inherent in focused regions, while DWRE prioritizes local energy information. This dual approach ensures that fine details and salient features are robustly identified and preserved during the high-frequency sub-band fusion process, overcoming the limitations of traditional focus measures.

Consistency Verification for Robust Fusion
A critical enhancement is the integration of a consistency verification (CV) mechanism. This step refines the initial decision map, ensuring that only consistently present and reliable information is carried forward. By mitigating erroneous selections and detail loss, CV significantly improves the integrity and visual quality of the fused high-frequency components, leading to a more robust and artifact-free final image.
