  • More information
    "SILAS softwar displays the pipelines as a clear hyperbola. This hyperbola is read by the software to be the probable top edge of an object. SILAS recognizes these contact points and presents the user with a marking of the object.The contact recognition consists of the automated determination of two parameters • Semblance of apex of hyperbola (top of contact). • Power of hyperbola."
