Quality comparison for Amaze and MG demosaicing algorithms
While doing RAW processing to develop photo and digital cinema, we strive to utilize sofisticated demosaicing algorithms to get better quality our of RAW.
Pro and Con for Amaze and MG algorithms
MG (Multiple Gradients) demosaicing algorithm is based on the idea to check many different gradients to discover best direction for color interpolation.
Amaze algorithm stands for "Aliasing Minimization and Zipper Elimination". It means that together with high quality demosaicing we can run additional modules to minimize aliasing and zipper artifacts. This is algorithm with GPL license.
Both algorithms are considered to be high-quality and they are utilized in well-known software. You can see Amaze at Raw Therapee, Fast Raw Viewer, MLV App and other applications. MG is a proprietory algorithm from Fastvideo company and you can see it at Fast CinemaDNG Processor software.
Pro for MG algorithm
- Performance is around 2 GPix/s on NVIDIA GeForce GTX 1080
- High PSNR/SSIM
- Good detection of gradients
- Internal sharpness
Pro for Amaze algorithm
- Performance is around 50 MPix/s on Intel Core i7 5930K CPU
- High PSNR/SSIM
- Aliasing minimization
- Zipper reduction
