Hello,

As I= had some questions on where do my speed numbers come from, here are some s= peed timings compared with x265 (very optmized HEVC) and Google WebP, on my= computer: Windows 10 64bit - Intel i5-6400 2.73Ghz 4C/8T, for a 512x512 .b= mp/ppm 24bit color image:

Encode time: x265: 310ms= =C2=A0 WebP: 70ms=C2=A0 NHW: 30ms
Decode time: x265: 30ms=C2=A0= =C2=A0=C2=A0 WebP: 40ms=C2=A0 NHW: 10ms

But the NH= W Project is totally unoptimized whereas x265 and WebP are extremely optimi= zed (multithreading, SIMD,...) and so with a good optimization (x4-5), the = NHW Project is 310/30x5=3D51.67x faster to encode and 30/10x5=3D15x faster = to decode than x265, and 70/30x5=3D11.67x faster to encode and 40/10x5=3D20= x faster to decode than WebP.

Also, I claim that t= he NHW Project has more neatness (subjective quality), and now I have devel= opped a NHW Neatness Metrics (that you can downlaod on my demo page) that i= s based on a neatness/perceived quality model, and that gives objective mea= surements and that objectively shows that the NHW Project has more neatness= .

To finish, I would be also very interested in yo= ur opinion if you have time on the new -l12 very high compression quality s= etting that I find very competitive!

Hello,

If i= t could be of interest, here are new speed measurement for -l13 very high c= ompression setting which are not the same.

For x26= 5 (HEVC), I use BPG codec, and this time I use -m 0 setting which uses the = fastest encoding setting of x265.I run the .exe 10x times and I pick the be= st scores.

So here are the timings at -l13 very hi= gh compression:

Encode time: x265 (BPG -m 0): 80ms= =C2=A0 NHW: 20ms
Decode time: x265 (BPG): 90ms=C2=A0 NHW: 10ms

So with an equivalent level of optimization (x4-5, m= ultithreading, SIMD,...), the NHW Project is 80/20x5=3D20x faster to encode= and 90/10x5=3D45x faster to decode than x265 (optimized HEVC)!

Hi,

Very so= rry for disturbing you, but for those interested who follow my work, I have= finally coded "extreme" compression for the NHW Project that is = competitive with HEVC.

I have also first really im= proved quality of the -l13 and -14 very high compression quality settings, = and so these settings are better.

I have started t= o code a -l15 "extreme" compression quality setting.I have tested= it on 15 rather good quality images and I find it competitive with x265 (H= EVC).

We can still save 2.5KB per .nhw compressed = files.


Finally,= I think I prefer coding extreme compression quality settings and improving= quality rather than adapting the NHW Project to any image size.For those w= ho would like to use the NHW Project on any image size and have a professio= nal use, and not a demo version, it would be so great if you could sponsor = me to develop the NHW Project (like adapting it to any image size).

Again if you are interested in the free open-source NHW P= roject, do not hesitate to contact me, as I am actively searching for a com= pany interested in the project.

I will also try no= w to not abuse of this list and post only when there are major improvements= and not few ones.
