OmniAlpha: Aligning Transparency-Aware Generation via Multi-Task Unified Reinforcement Learning
arXiv CS.CV

ArXi:2511.20211v2 Announce Type: replace Transparency-aware generation requires modeling not only RGB appearance but also alpha-based opacity and cross-layer composition, which are essential for tasks such as image matting, object removal, layer decomposition, and multi-layer content creation. However, existing RGBA-related methods remain largely fragmented, with separate pipelines designed for individual tasks.
