Multi-focus image fusion based on dynamic threshold neural P systems and surfacelet transform

作者：

Highlights：

• We propose a dynamic threshold neural P (DTNP) system with local topology.

• We develop a multi-focus image fusion framework based on DTNP systems in ST domain.

• We propose a fusion rule based on DTNP systems for low-frequency ST coefficients.

• We propose a fusion rule based on DTNP systems for high-frequency ST coefficients.
