Noise Reduction in Video Sequences The State of Art and the Technique for Motion Detection

Reeja S.R, N. P. Kavya
2012 International Journal of Computer Applications  
This paper provides a detailed state of the art of different video denoising techniques. Most of the video denoising algorithms are done through the motion detection technique.  ...  The main goal is to give a survey of various noise reduction techniques for video. Object detection is the first level of video denoising. The first level can be achieved through Motion Detection.  ...  MOTION ESTIMATION AND MOTION COMPENSATION By the use of recursive temporal filtering motion estimation enables us to fuse images and then reconstruct a high resolution image.  ...

Space-Time Adaptation for Patch-Based Image Sequence Restoration

Jerome Boulanger, Charles Kervrann, Patrick Bouthemy
2007 IEEE Transactions on Pattern Analysis and Machine Intelligence  
We present a novel space-time patch-based method for image sequence restoration. We propose an adaptive statistical estimation framework based on the local analysis of the bias-variance trade-off.  ...  Experiments show that this method is able to drastically improve the quality of highly corrupted image sequences.  ...  A similar exploitation of a parametric motion compensation was proposed in [9] and associated with a 3D Wiener filtering technique.  ...

Video Denoising via Empirical Bayesian Estimation of Space-Time Patches

Pablo Arias, Jean-Michel Morel
2017 Journal of Mathematical Imaging and Vision  
The high dimensionality of spatio-temporal patches together with a limited number of available samples, poses challenges when estimating the statistics needed for an empirical Bayesian method.  ...  We demonstrate empirically that these estimators lead to better empirical Wiener filters.  ...  Early works proposed temporal or spatio-temporal filters which either compensate for motion using estimated motion trajectories or used some kind of mechanism to adapt to the temporal changes in the video  ...
