algorithm variation » algorithm validation (Expand search), algorithm evaluation (Expand search), algorithm derivation (Expand search)
coder detection » code detection (Expand search), border detection (Expand search), corner detection (Expand search)
variation upon » variations upton (Expand search), variation among (Expand search), variation using (Expand search)
using coding » using coping (Expand search), using coating (Expand search), using cooking (Expand search)
