24.3 Spectral Feature-Based Coding

Recently, Qian et al. (1996) proposed a spectral feature binary coding (SFBC) that extended the SPAM binary coding as follows.

Let

(24.13)

where MD is the spectral signature mean deviation given by . Concatenating s^a, s^b and defined in (24.2), (24.3), and (24.13), respectively, creates a new -dimensional binary code word, referred to as SFBC defined by

(24.14)

Similarly, we can define the spectrals median partition deviation (MPD) by

(24.15)

and

(24.16)

In analogy with the Qian et al.'s SFBC we can concatenate the L-dimensional binary code word defined by (24.16) to the MP binary code word to create a new MP spectral feature-based -dimensional binary ...
