banding.md

keywords are usually debanding, bit depth expansion, false contour removal, decontouring

CCL-based stuff only works on banding that stems from heavy compression (i.e. completely flat bands) and falls apart with flat content

Debanders

Knowledge-based

• AdaDeband: https://sci-hub.st/http://dx.doi.org/10.1109/LSP.2020.3024985 (https://github.com/google/bband-adaband - shit code kinda slow and CCL based)
• Baugh: https://sci-hub.st/http://dx.doi.org/10.1145/2668904.2668912 (https://github.com/baughg/debanding - pretty different code from paper and CCL based)
• BEF-BDE: https://ieeexplore.ieee.org/document/9496257 (https://gist.github.com/noizuy/ce2d377a5642b1d9191368abd708b9c4)

• AV2: https://ieeexplore.ieee.org/document/10125298 (https://gitlab.com/joelsole/avm/-/commit/bb07c0dd2f5c1e4200cdc054720775fea7391434 - kinda okay but dies with flat content)
• Lee: https://ieeexplore.ieee.org/document/1706513 & https://ieeexplore.ieee.org/document/1605045 & http://dx.doi.org/10.1109/TCE.2010.5506014 (https://gist.github.com/noizuy/193cca51e9d66c59bcc58524add2d392 - direction estimation is slow and the smoothing isn't the fastest but still acceptable)
