Morphological correction

Open a dialog to change the detected features by making mathematical morphology operations.

Types of correction

The images shown hereafter are obtained from the following source image:

006MorphoSource

006MorphoErosion

Erosion

Erosion discards one line of pixels around each object.

006MorphoDilation

Dilation

Dilation adds one line of pixels around each object.

 

 

 

 

006MorphoOpening

Opening

Opening consists in applying a dilation and an erosion one after another which results in opening the objects and separating grains hardly touching one another.

006MorphoClosing

Closing

Closing consists in applying an erosion and a dilation one after another which results in closing the objects and in melting the grains hardly touching one another.

Conditions

Strength

Strength or sensitivity of the morphological operation.

A 3x3 square is used as a structuring element. When the square moves over the image, at a given position, there is an intersection of 0 to 9 of its pixels with the pixels of the image's object.

006MorphoStrength

When choosing the maximum strength of 4, an intersection with only 1 pixel of the structuring element is enough to add a pixel to the object (dilation). or to discard a pixel from the object (erosion).

When choosing the strength of 1, an intersection with at least 4 pixels is needed to discard or add a pixel.

Iteration

Number of times the correction is applied.

Max. value: 5

Remove grains touching the edges

If you check this option, the resulting image will be freed from all the grains touching one of the image edges. This enables you to work only on whole objects that are not cut by the edges of the image.

Merge contiguous grains

If two or several grains touch each other after the correction, these contiguous grains can be merged into a single bigger grain.
