A New Approach to Model Pitch Perception Using Sparse Coding
Fig 8
Detailed results for f0 = 606.4Hz.
The selected examples are taken from Fig 7 and show the SC coefficient vectors h and the pdfs for the two dictionaries and for the two amplitudes. (A, C) The SC coefficient vectors h for the Dsine and Dstack dictionaries, respectively. (B, D) The resulting pdfs, over one octave around f0 = 606.4Hz, for the Dsine and Dstack dictionaries, respectively. Note the difference between the SC coefficients of the two dictionaries, but the qualitative resemblance between the two pdfs.
