Fill Hole

Description

Fills the holes found in a particle. The holes are filled with a pixel value of 1. The source image must be an 8-bit binary image. The holes found in contact with the image border are never filled because it is impossible to determine whether these holes are part of a particle. Type : polymorphic.

Input parameters

Image Src : class, type accepted U8.
Connectivity 4/8 (8) : boolean, specifies the type of connectivity used by the algorithm for particle detection. The connectivity mode directly determines whether an adjacent pixel belongs to the same particle or a different particle.

• • True : particle detection is performed in connectivity mode 8
  • False : particle detection is performed in connectivity mode 4

Output parameters

Image Dst : class
