Pixelwise(SEGS - SEGS)

ImpactPack/Operation

SubtractMaskForEach

Removes only the overlapping areas between the masks included in base_segs and the mask regions of mask_segs. SEGS with no overlapping mask areas are filtered out.

Example

JSON Example

{
  "class_type": "SubtractMaskForEach",
  "inputs": {
    "base_segs": [
      "node_id",
      0
    ],
    "mask_segs": [
      "node_id",
      0
    ]
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
base_segs	SEGS	required	-	-
mask_segs	SEGS	required	-	-

Outputs

Index	Name	Type	Is List	Connection Reference
0	SEGS	SEGS	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this SubtractMaskForEach node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• SEGS (SEGS): ["5", 0]
