Classify objects using pixel classification from external files.

Parameters

Category

Choose the category to which the external file should be applied.

File

Choose the file containing the pixel classification.

Min area

The minimum number of pixels for an object to be included.

Max area

The maximum number of pixels for an object to be included.

If 0 no maximum area is defined.

Object filter

Use an expression to further exclude unwanted objects based on shape.

Properties that can be used for the Expression:

  • Area

  • Length

  • Width

  • Circumference

  • Regularity

  • Roundness

  • Angle

  • D1

  • D2

  • X

  • Y

  • MaxBorderDistance

  • BoundingBoxArea

For details on each available property see: Object properties Details

Shrink

Takes away x numbers of pixels at the borders of the objects included in images.

Separate

  • Normal

    • Can have both separated and combined objects.

  • Separate adjacent objects

    • All objects are defined separately.

  • Merge all objects into one

    • All objects are defined as one.

  • Merge all objects per row

    • All objects per row segmentation are defined as one.

  • Merge all objects per column

    • All objects per column segmentation are defined as one.

Only visible when applicable

Link output objects from two or more segmentations to top segmentation. Descriptors can then be added to the common object output and will be calculated for objects from all segmentations.

Descriptors after object will be calculated for all three segmentations (Sample1, Sample2 and Sample3)

The segmentations must be at same level to be available for linking.
