Hyperspectral and SAR Image Classification via Multiscale Interactive Fusion Network
Summary
This study introduces MIFNet, a novel method for classifying multisource remote sensing data. It effectively extracts multiscale features and fuses data from hyperspectral and synthetic aperture radar (SAR) images, improving classification accuracy.
Area of Science:
- Remote Sensing
- Computer Vision
- Machine Learning
Background:
- Single-source data presents limitations in remote sensing image classification.
- Existing multisource data fusion methods struggle with effective feature extraction and fusion.
Purpose of the Study:
- To propose a novel method, MIFNet, for joint classification of hyperspectral and synthetic aperture radar (SAR) images.
- To address limitations in single-source feature extraction and multisource feature fusion.
Main Methods:
- Developed a multiscale interactive information extraction (MIIE) block for richer scale information and reduced model complexity.
- Introduced a global dependence fusion module (GDFM) for cross-attention and long-range dependence capture between multisource data.
Main Results:
- The proposed MIFNet method demonstrates superior performance on three benchmark datasets.
- Experiments confirm the effectiveness of both the MIIE block and GDFM module in enhancing classification accuracy.
Conclusions:
- MIFNet offers an effective solution for hyperspectral and SAR image classification using multisource data.
- The proposed modules are crucial for improving the accuracy of remote sensing image classification.

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
