Image Enrichment Using Data Fusion (210)
Problem: Need semi-automated, statistical tools for feature extraction & change assessment from multi-mode images
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis System Applications
PNNL Solution:
- Developed unique image fusion methods
- Sharpened low resolution images using inverse Kriging method
- Used Conditional Mixing Model on high spatial resolution images to sharpen high spectral resolution images
- Developed unique methods for 2-d feature extraction, change assessment & to exploit spatial relationships of image features
Capabilities Employed to Meet Client Needs: Statistical tools for data analysis; unique image fusion techniques including: a) inverse Kriging to sharpen a low spatial resolution image (based on a small subset overlapping a high spatial resolution image); b) Conditional Mixing Model uses high spatial resolution imagery to sharpen high spectral resolution imagery (these images do not have to overlap in spectral regions); and c) developed Hidden Markov Model for unique 2-d feature extraction and change assessment, and to exploit spatial relationships of targets.
