<div dir="ltr"><div>Hello,</div><div> </div><div>I have just added a higher quality setting for the NHW codec (-h3, +4/5Ko), with extended residual coding on 512x256 wavelet image and more higher wavelet coefficients.This setting has more precision.</div>
<div> </div><div>I have also tried for the -l3 lower quality setting to raise the quantization from 0.77 to 0.79, and then remove 1Ko with a fast denoising (exp, actually I use data computed during pre-processing function in the encoder, and so this simple denoising is at nearly no extra computational cost).The -l3 setting would have then a little more precision, but don't know if it is better (would still have to better select the wavelet coefficients...).Any comment is welcome.</div>
<div> </div><div>I have updated my demo page: <a href="http://nhwcodec.blogspot.com/">http://nhwcodec.blogspot.com/</a> .</div><div> </div><div>Many thanks,</div><div>Raphael</div><div> </div></div><div class="gmail_extra">

<div dir="ltr"><div>Hello,</div><div> </div><div>Just a very quick message to let you know that I have added a higher quality setting (-h2, +10Ko) and I have added now residual coding on the 512x256 wavelet image for the higher settings.Precision is a little better.-I also still apply the post-processing function on the 512x256 wavelet image for now.-</div>
<div> </div><div>Here is the link for the binaries (as I can not link them in my blog for now): <a href="https://docs.google.com/file/d/0B9F8eU1TkGfiVDdFZkpWd3I2ZDQ/edit?usp=sharing" target="_blank">https://docs.google.com/file/d/0B9F8eU1TkGfiVDdFZkpWd3I2ZDQ/edit?usp=sharing</a></div>
<div> </div><div>For the lower quality settings, will have to improve the -l3 setting first, raise the quantization to something like 0.82 for example for -l3 and -l4 settings, and better select/remove the wavelet coefficients.</div>
<div> </div><div>Many thanks,</div><div>Raphael</div><div> </div><div> </div><div> </div><div> </div></div>
