  temporal filtering
In this work, a new method to deal with the unconnected pixels in motion compensated temporal filtering (MCTF) is presented, which is designed to improve the performance of 3D lifted wavelet coding.
      
Furthermore, multiple description scalable coding (MDSC) is investigated, and novel MDSC schemes based on 3D wavelet coding are proposed, using the lifting implementation of temporal filtering.
      
The PRNS procedure uses temporal filtering to define large-scale turbulence, and the model developed to account for unresolved scales is grid independent.
      
For many reasons, temporal filtering may be more natural, particularly for flows of engineering interest.
      
Temporal filtering from perceptual processing is not sufficient to account for the discrepancies between neural and psychophysical ratios.

  filtering in the time domain
They are compared with the SSH from the Topex/Poseidon altimeter after suitable filtering in the time domain to remove smaller time and length scales.
      


The article theoretically analyzes the impact of self phase modulation caused by nonlinear refractive index on ultrashort pulse. A new method, temporal filtering, is proposed for improving quality of femtosecond laser pulse. After analyzing the result of simulation, it is found that the filter method can narrow pulse and enhance the intensity of pulse. The approach can improve the quality of femtosecond pulse.

Video denoising algorithms based on discrete wavelet transform (DWT) do not allow real-time processing due to their huge computational complexities. To overcome the shortcoming, a new real-time algorithm for video denoising based on lifting scheme was proposed. First, each frame of the video was decomposed into multi-level wavelet to obtain the scaling coefficients and the wavelet coefficients by using lifting scheme. Then, each level of wavelet coefficients was filtered by soft-threshold algorithm. After the...

Video denoising algorithms based on discrete wavelet transform (DWT) do not allow real-time processing due to their huge computational complexities. To overcome the shortcoming, a new real-time algorithm for video denoising based on lifting scheme was proposed. First, each frame of the video was decomposed into multi-level wavelet to obtain the scaling coefficients and the wavelet coefficients by using lifting scheme. Then, each level of wavelet coefficients was filtered by soft-threshold algorithm. After the inverse wavelet transform, temporal filter was applied on the filtered video to enhance the denoising effect further. Experiments show that this algorithm has better quality in terms of real-time processing and denoising effectiveness.
