Hyperspectral Imaging

Newly emerging alternative to multi spectral imaging is hyperspectral imaging. In this technique, physical and biophysical characteristics are identified with the contiguous narrow spectral band where as in conventional multi spectral imaging likelihood is the features to discriminate the object not to identified the object.

Wavelet transformation and analysis can be used for the spectral analysis as the wavelet has the tools to decompose the signal into average and details with multiresolutional analysis.
