Hello, 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.- Here is the link for the binaries (as I can not link them in my blog for now): https://docs.google.com/file/d/0B9F8eU1TkGfiVDdFZkpWd3I2ZDQ/edit...

Hello, I have finally added 2 lower quality settings for the NHW codec: -l1 (-5Ko) and -l2 (-10Ko).I use a quantization of 0.935 and 0.88 (kind of quantization), and I decrease residual coding on the first order wavelet image. I have updated the demo page: http://nhwcodec.blogspot.com/ . These 2 lower quality settings are still experimental.If you could find time, would be interested in any

...er quality settings (because for these settings the residual coding is on the first order (256x256) wavelet image and for quite blurred images there is not enough energy, information in this band), but the results can be good with the higher -h2 and -h3 quality settings with larger residual coding (512x256, more information). My question is, if I detect that an image is quite blurred (in the preprocessing function, if for example the 4/5th of the pixels have a segmentation kernel result under 60/70 then the image can be considered as quite blurred) then I increase quality setting and select now the...

...raw call is used by textureSize() and textureQueryLevels() (instead of the currently bound texture). The attached program demonstrated the bug. When the program is built with -DBROKEN, it incorrectly prints "width: 2.000000 height 2.000000 miplevels 2.000000" while the current texture is 512x256 with 4 miplevels.

Hi again, I have improved precision of my codec (on the encoder and decoder).I have also improved the -h1 quality setting.-Source code and binaries at http://nhwcodec.blogspot.com/-. I am still trying to improve precision of my codec, with keeping my low-complexity (fast) approach. I do not totally use the reference (and impressive) block prediction with different modes + residual coding scheme,
