"Data fusion is the process of integrating multiple data sources to produce more consistent, accurate, and useful information than that provided by any individual data source."
The integration of data from multiple sensors or platforms, often with different spatial, spectral, and temporal resolutions, to improve the overall quality and usefulness of remote sensing data.
Remote Sensing: It involves collecting data from a distance using sensors and satellites.
Imaging: It involves capturing and analyzing images obtained through remote sensing.
Spectral Analysis: It involves analyzing the electromagnetic spectrum to identify and characterize objects.
Classification Techniques: It involves categorizing remote sensing data based on specific criteria.
Data Preprocessing: It involves preparing and cleaning remote sensing data for analysis and integration.
Data Fusion Algorithms: It involves combining data from multiple sources to generate comprehensive information.
GIS (Geographic Information System): It involves creating, analyzing, and interpreting spatial information.
Machine Learning: It involves training algorithms to identify and classify patterns in remote sensing data.
Decision-making Processes: It involves using remote sensing data to make informed decisions about natural resources, land use, and environmental management.
Feature Extraction: It involves identifying and extracting specific features from remote sensing data for analysis.
Signal Processing: It involves filtering, analyzing, and transforming remote sensing data signals to produce relevant information.
Accuracy and Quality Assessment: It involves validating remote sensing data to ensure the accuracy and quality of the information.
Image Registration: It involves aligning and matching different images obtained from remote sensing data for analysis.
Sensor Fusion: It involves combining data from multiple sensors to generate a single comprehensive image.
Data Mining: It involves analyzing large amounts of remote sensing data to identify hidden patterns and relationships.
Image Fusion: Combining multiple images of the same area to produce a composite image that contains more information than the individual images. This can improve resolution, reduce noise, and enhance features.
Data Integration: Combining data from different sources, such as satellite missions, ground-based sensors, and models, to create a more complete picture of a particular phenomenon or process.
Decision Fusion: Combining the outputs of multiple algorithms or models to make a final decision about a particular event or condition.
Sensor Fusion: Combining data from different sensors, such as passive and active sensors, to produce a more accurate and detailed image of a particular area or object.
Temporal Fusion: Combining data from multiple images or datasets that were acquired at different times to track changes over time or identify patterns in long-term trends.
Spatial Fusion: Combining data from multiple images or datasets to create a more detailed map of a particular area or feature, such as topography, vegetation, or land use.
Spectral Fusion: Combining data from different parts of the electromagnetic spectrum, such as visible, infrared, and microwave, to identify different materials or properties of a particular area or object.
Feature-Level Fusion: Combining data from different features within the same image, such as edges or textures, to create a more detailed representation of a particular area or object.
Knowledge-Based Fusion: Combining data with prior knowledge or domain expertise to improve the accuracy and usefulness of the final output.
Object-Level Fusion: Combining data from multiple sources to detect and track objects or events, such as wildfires, floods, or landslides.
"Data fusion processes are often categorized as low, intermediate, or high, depending on the processing stage at which fusion takes place."
"Low-level data fusion combines several sources of raw data to produce new raw data."
"The expectation is that fused data is more informative and synthetic than the original inputs."
"For example, sensor fusion is also known as (multi-sensor) data fusion and is a subset of information fusion."
"The concept of data fusion has origins in the evolved capacity of humans and animals to incorporate information from multiple senses to improve their ability to survive."
"A combination of sight, touch, smell, and taste may indicate whether a substance is edible."
