This study introduces a novel network for multi-focus image fusion, improving global context modeling and feature separation. The frequency-adaptive transformer enhances efficiency and accuracy in creating a single, clear image.

Area of Science:

  • Computer Vision
  • Image Processing

Background:

  • Multi-focus image fusion combines images with varied focal planes into one sharp image.
  • Current methods struggle with global context and precise feature separation.

Purpose of the Study:

  • To develop an advanced network for multi-focus image fusion.
  • To overcome limitations in existing fusion techniques regarding context and feature handling.

Main Methods:

  • Proposed a network integrating a fusion interactive mask decoupling mechanism and a frequency-adaptive transformer dual mechanism.
  • Utilized Fourier transform for efficient frequency-domain attention computation and adaptive blocking.
  • Implemented a dynamic mask-guided feature decoupling strategy for targeted foreground, background, and global context fusion.
