Detailed Description

Binary morphological operations on normalised float masks.

Pure functions. No MayaFlux type dependencies.

Conventions

• Input masks are single-channel float where 1.0f is foreground and 0.0f is background. Values are treated as binary: >= 0.5f is foreground, < 0.5f is background.
• Output is strictly binary: 1.0f or 0.0f
• w and h are pixel dimensions; caller ensures span size == w * h
• radius is the structuring element half-size in pixels. A radius of 1 produces a 3x3 square structuring element.
• Border handling is clamp-to-edge throughout
• Parallelism handled internally via Parallel::par_unseq
