| Abstract: | The principle of filter1ng different type 0f noise with wavelet transf0rm, in which include de-terminative and rand0rn, and advantage c0mpared with F0urier transf0rm is systematic studied. A numberof m0dified versi0n of a denoising a1gorithm is discussed. The algorithm 0f the empirica1 estimation is pr0-posed for the purpose of denoising. The presented result has a practical w0rth f0r app1icati0n to an engi-neering. |
