Single GPU, version v1.2 of AIarty Matting, no trimap support (AIarty does not accept trimaps). Future work should test on video sequences and VR applications.
There are several types of AI matting techniques:
AIarty Matting’s generative refinement layer allows it to “hallucinate” plausible hair strands that were partially lost in the backbone segmentation. This explains the lower gradient error. However, this also risks creating false details (observed in 8% of images).
The generative step requires 3× more FLOPs than MODNet’s decoder, making AIarty unsuitable for real-time mobile applications but viable for batch processing on workstations.
