| About the selecting of atoms [ Reply ] By: Ji Haiyan on 2007-07-24 07:00 | [forum:3733] |

Hello, From MPTK source code, I can see the size of the dictionary you created according to the blocks has relation with the signal to be analyzed. And before starting iteration, the atoms in the dictionary do not form completely, only a window defined in the block forms. From the STFT results between the window formed and the signal analyzed, how you choose the best frequency of an atom. And given a fixed frequency, how to deduce the phase and the amplitude of the atom, I do know you use which formula to deduce them, this puzzles me a lot. Hope you give me a specific description about this point. Looking forward to your response. Regards! |
