We introduced the noise reduction technique in Eulerian video motion magnification based on wavelet domain filters.The goal of this paper is to reduce noise in subtle video motion Magnification and amplify temporal variations to reveal imperceptible changes which are difficult to see with naked eye.The input to this method is a standard video sequence, then spatial decomposition is applied followed by temporal filtering to the frames which is called "Eulerian Video Magnification".The obtained signal is magnified to disclose hidden information.In the proposed method the amplified temporal variations are de-noised with combined spatial filter in wavelet domain and temporal filter to give noise free results in videos.We exhibit the advantages of this approach on natural and synthetic video sequences, and explore applications in visualization, video enhancement and scientific analysis.
