Hello, For those interested (and yes, also to keep the topic warm), I have released the NHW v0.3.0-rc10 new version. I continue to fine-tune the nhw_kernel weights and pre_processing.This new version has then more precision and a better visual quality.

Hello, I have released the NHW v0.3.0-rc4 new version. Yes I am slowing down my work on NHW, as I tried quite complex nhw_kernel weight computation formulas, but finally it is this trick that seems to do the work and seems to bring a visual quality improvement.This new version has then more precision (hope my eyes were not too much tired).

Hello, Another quick update, improving the nhw_kernel weight computation seems quite complex (for me), I even try rather simple things that in theory should work, but at final visual inspection, the visual quality was not better.I will also have now to quasi-put on pause the NHW development, maybe in 5 or 6 months will pop up a good idea... That's also totally right that I should stop

Hello Spork, Thank you very much for your great help! So ok, let's create a website for the NHW Project! Anyone who wants to help is very welcome! Do you want we start first with wix.com or rather from nearly scratch? I think from scratch would be better as we can really do what we want, but it will be a lot and lot more difficult to make... -I will send you a private email for the USB

I don't mind at all. I imagine there are more people like me out there who have been following your work, but haven't said anything. I agree that a series of pages explaining how things work may lead to more contributions. At the very least it would lead to more people being better educated on how wavelets work in image compression. But, this is your project, if you don't have the

Hello, Just a quick message to let you know that I have really improved very high compression of the NHW Project from -l8 to -l13 quality settings, and we can still save 2.5KB per .nhw compressed file. Actually I am new to very high compression, it is just 3 months that I am working on it (I put on pause the NHW Project from August 2013 to February 2018 )... And I realize that very high

Hello, The -l8 "very high compression" setting I posted was not really good.Now I have corrected and improved it, and now the -l8 quality setting is really better, more precision and more neatness. I think now it is a good setting, and I have started to compare it with x265 and it can be now competitive. More at: http://nhwcodec.blogspot.com/ Do not hesitate to test it and give me

Hello, I forgot in my last reply that my DWT implementation can be speed up, for example I'm doing for now: for (;_X1<_E_;_X1++,_RES+=2) //dilatation { _RES[0]=_X1[0]<<3; _RES[1]=(_X1[1]+_X1[0])<<2; } then for (;_X2<_E_;_X2++,_RES+=2) //details { _RES[0]-=(_X2[1]+_X2[0])<<1; _RES[1]+=6*_X2[1]-_X2[2]-_X2[0];

> How about macOS? Can you give us a build. I don't have a macOS environment so I won't be able to give you a build.But it would be also great to have a macOS version.I think now that many bugs have been corrected, and that the NHW Project can compile ok under clang and run ok on macOS. If a forum member, that runs macOS, could give us a build and first let us know if the code is ok,

Raphael, Some 15 years ago I implemented limited functionality Theora in our cameras FPGA (it took me 6 month of hard labor), and then gave up - it is a very crowded space and it is difficult to compete with more advanced codecs. And for our other work we anyway need almost raw image data, so we are using JPEG-based JP4 format (https://community.elphel.com/jp4) that we originally developed for

Hi Andrey, Thank you for your answer.Actually, NHW is very low-power so I think it could be geared toward any hardware.But actually I don't have hardware skills, so NHW is not a real hardware project for now maybe? I agree with you that it is extremely difficult (for me) to build a community around NHW, I'm certainly very bad/underskilled at it.Any help is welcome! Cheers, Raphael Le

Great!!! Do not hesitate to let me know if it works ok for you! Cheers, Raphael 2018-04-16 22:59 GMT+02:00 David Willmore <davidwillmore at gmail.com>: > That's great news!

Hello, I have improved a little the NHW codec.I have improved the dequantization in the wavelet HH band, and little improved the -l2 (and lower) quality setting.I have also added a -l3 lower quality setting (-15Ko, exp), I have increased the quantization for this other setting, and I start to remove higher wavelet coefficients, but this is not optimal... The artifacts start to be noticeable for
