New Release 0.3.0-rc37
Link: Updated 11/16/2024 windows binaries / source code on GitHub
Developed compression settings: -q9 to -q23
11/16/2024: v0.3.0-rc37 version.Better neatness, better precision, still very fast!
10/09/2018: I have developped NHW Neatness Metrics to measure neatness of images.
An Image Comparison of NHW and x265 Sample 512x512 test images
Here are the 3 test images compressed with this new version 0.1.6:
Lighthouse1.nhw 30402octet |
Birds5.nhw 44227octet |
Butterflies2.nhw 41871octet |
Remark: The entropy coding schemes are not totally optimal for now, I have the fast ideas to improve them, and so we can save 2.5KB per .nhw compressed file in average.
Next steps are: coding the other (lower and higher) quality settings, lower quality setting is rather complex...
Many thanks,
