Opening by Reconstruction Operator

Building the Cantata Workspace


To build a workspace to experiment with the opening by reconstruction operator:
  1. Choose Gaussian Noise from Generate Noise in option Input/Output. Use Width = 20, Height = 1, Mean = 50 and Variance = 20.

  2. Apply the morphological Subtraction (mmach) to subtract a constant 6 of the generated noise.

  3. Generate a 3x3 Str.El. Flat Structuring Element like the following:
               0 0 0
               1 1 1  Structuring element used
               0 0 0
    

  4. Apply the Opening by Reconstr. operator using as first input the generated noise, as second input the result of the subtraction and as third input the structuring element.

  5. Visualize the result using the Plot Display 2D in Visualization.
