Input signal and wavelet approximation coefficients of the input signal. Top graph: An example of the part of the input signal for the wavelet decomposition algorithm. Both red and green channels are shown. The signal is assumed to be zero for the missing data (gaps) in the genomic regions without any probes on the tiling array. Second, third, and fourth graphs from the top: approximation coefficients A(m) of the input signal for the decomposition levels m = 6, 7, and 8.
