Cyclic Wiener Filtering Algorithm in Discrete Cosine Transform Domain for Vibration Signal
MATEC Web of Conferences, 2016 In order to solve the problem that the effect of using cyclic Wiener filter directly to remove the noise on the non-stationary vibration signal is poor, the paper applies discrete cosine transform to the cyclic Wiener filter, proposing the cyclic Wiener ...

Hybrid Algorithm Based on Hyper Spectral Noise Removal for Satellite Image
EAI Endorsed Transactions on Energy Web, 2020 Usually the image obtained from a sensor is blurred by noise. Such noises are identified and eliminated by the procedure called denoising. The cross breed (Hybrid) algorithm is a popular technique that has been utilized recently.
