Dear Sirs or madams,
I am writting you to have some details about the yuvdenoise filters.
I am currently working on the improvement of compressed video quality with a
preprocessor. I study state of the art of denoising and pre-filtering
techniques in compression context.
I have tested the yuvdenoise filter of Mjpegtools, which you developped, as
preprocessor before compression, and I found very interesting results even for
sequences not corrupted by noise, especially for the temporal filter followed
by the « median 3D » filter.
I
would like to have some precisions concerning the concept of this processing
(temporal
filtre + post medain 3D filter), in order to understand why your algorithm is
more effective than certain elaborated denoising filter. For these reasons, I
wonder if you could communicate me some references of your work.
Thanks for your time, I look
forward to your reply,
Kind regards,
Eloïse Vidal
