This paper presents an image denoising algorithm, which applies bilateral filtering (BLF) in the Laplacian subbands.  ...  Specifically, an image is Gaussian filtered to obtain a low band image, and the low band image is subtracted from the original to have the high band signal, which forms the Laplacian subbands.  ...  Acknowledgements This work was supported in part by Samsung Electronics, and in part by the Ministry of Science, ICT and Future Planning, Korea, through the Information Technology Research Center support  ...

Hence, the denoising algorithm in this study has better denoising effects on ultrasound images than traditional algorithms, with higher definition and less noise and artifacts.  ...  The admission age of the children in group 1 was significantly younger than that of group 2, the bilateral stone rate was significantly higher than that in group 2, and the difference was statistically  ...  Acknowledgments is work was supported by grants from the Science and Technology Bureau of Sichuan Province (21ZDYF1329).  ...

We propose a generic scheme that extends existing denoisers such as the bilateral filter to account for all the problems above.  ...  Common noise characteristics in such images originate from camera-internal processing, such as demosaicing, tone mapping, and JPEG compression.  ...  Furthermore, the filtered items are the mid/high frequency subbands (statistically different than natural images), making it difficult to leverage the prior works on denoising algorithms or statistical  ...
