Mask Logic Operation

Function Description

Performs pixel-wise logical operations on two groups of mask images of the same size.

Use Cases

General-purpose logical operation step for mask lists, with no fixed application scenario.

Inputs

• Mask Images (Required): A group of mask images.

• Reference Mask Images (Required): Another group of mask images (same size as the first group).

Outputs

• Mask Images: Mask images after logical operation.

Parameters

• Bool Logic Type

  Selects the type of logical operation to perform, including the following options:

  • AND: Extracts the common parts of the two masks.

  • OR: Merges the two input masks.

  • XOR: Removes the common parts of the two masks.

  • NOT: Performs inversion operation on the first input mask image. Black parts (usually background) become white, and white parts (usually object contours or edges) become black.

• Correspondence Type

  This parameter specifies the correspondence relationship between masks in the two input mask lists. When NOT operation is selected, there is no correspondence type parameter.

  • FirstToAll: Only uses the first mask in the second group, corresponding to the first group of masks.

  • OneToOne: Default value. Uses all masks in the second group, corresponding one-to-one with the first group of masks.
