Is it not sufficient to extract features only at DWT decomposition level 3?

02 February 2013 1 10K Report

If we are including features of level 1 and 2, why decompose up to level 3, as level 1 and 2 features must be stronger than level 3?

Hariharan M

It depends on the one/two dimensional signals....Need to investigate the signals after 3rd level decomposition.........we can apply optimization techniques to decide number of decomposition and number of wavelet features.........
