Halos
Halos refer to the visible artifacts or fringing that often appear around the edges of a subject during digital masking or compositing. They typically manifest as bright or dark outlines where the foreground and background colors contrast sharply, resulting from imperfect edge detection or color spill.
Context: AI-Driven Edge Refinement
Recent advancements in generative AI and machine learning have targeted the reduction of halos in complex masking scenarios, particularly for fine details like hair and fur.
- Photoshop’s Enhance Edge AI: Adobe introduced an AI-powered “Enhance Edge” feature in Photoshop Beta 27.11.0 to address persistent issues with complex selections.
- Hair Masking: The primary use case for this feature is improving the accuracy of hair masking, a traditionally difficult task due to the semi-transparent and intricate nature of hair strands.
- Artifact Reduction: The AI specifically targets the elimination of halos and other edge artifacts that occur during standard selection processes.
- Generative Credits: The implementation utilizes generative AI capabilities, which consume Generative Credits within the Adobe ecosystem.
