Abstract
- Donnoho et have proposed a method for de-noising by threshold, which has been used in many signal de-noising and compression problems. But the method of Dohono is not successful for impulsive noises. We have proposed a method, which detect and wipe off impulse noise, then de-noising by shift-invariant wavelet . Simulation results indicate that: it can better detect and reduce the impulsive noise and it can reduce the noise while keeping the signal edges better compared to other wavelet based denoising algorithms.
