Research direction

The issue names no files, tests, or entry points. Start by locating the existing alpha-masking implementation and its tests, then review how the listed threshold, random-walker, sieve, edge-shape, and majority-filter approaches would be evaluated. Done means selecting and documenting an alternate masking function with clear comparison results.
