Cross-scale coefficient selection for volumetric medical image fusion

Area of Science:

• Medical Imaging
• Image Processing
• Computer Vision

Background:

• Joint analysis of multi-modal medical data is increasingly common.
• Image fusion techniques are crucial for combining and enhancing information from different imaging sources.
• Existing fusion methods may not fully exploit multiscale information or consistencies.

Purpose of the Study:
