#initialize(dest, source, default, zero, labels, rank, n) ⇒ Components

Constructor

Parameters:

  • dest (Node) —

    Target array to write component labels to.

  • source (Node) —

    Array to extract components from.

  • default (Node) —

    Value of background pixel.

  • zero (Node) —

    Zero is used to aid compilation.

  • labels (Node) —

    Array to store label correspondences.

  • rank (Node) —

    Array to store number of indirections for each label.

  • n (Node) —

    Pointer to return number of components.
