Topic: Spectrogram, Cepstrum and Mel-Frequency Analysis
• Speech is analyzed over short analysis window • For each short analysis window a spectrum is obtained using FFT • Spectrum is passed through Mel-Filters to obtain Mel-Spectrum • Cepstral analysis is performed on Mel-Spectrum to obtain Mel-Frequency Cepstral Coefficients • Thus speech is represented as a sequence of Cepstral vectors

Introduction to Hyperspectral Image Analysis
spacejournal.ohio.eduThere are many unique image analysis algorithms that have been developed to exploit the extensive information contained in hyperspectral imagery. Most of these algorithms also provide accurate, although more limited, analyses of multispectral data. Spectral analysis methods usually compare pixel spectra with a reference spectrum (often called a ...
