Status Summary
What is hyperspectral image?
How to analyze hyperspectral image?
Why reduce dimensionality in hyperspectral image analysis?
What is independent component analysis?
How to use ICA to reduce dimensionality in HSI?
Any parallel solution?
Implement on FPGA?
Multispectral Image
Simplest one: RGB images
Not necessarily contiguous
Multispectral sensor collect data
Simultaneously
Sequentially
Hyperspectral Image
In narrow and contiguous wavelength bands.
Most Hyperspectral
100~300 bands
Interval < 15 nm
Hyperspectral sensor collect data
Simultaneously
Conclusions
HSI and HSI Analysis
Reduce dimensionality
ICA
Using ICA to reduce dimensionality
Parallel ICA
Implement on FPGA
