obj_diffobj_diffObjDiffObjDiff (Operator)

Name

obj_diffobj_diffObjDiffObjDiff — Calculate the difference of two object tuples.

Signature

Description

obj_diffobj_diffObjDiffObjDiffObjDiff calculates the set-theoretic difference of two object tuples: (objects in Objects) - (objects in ObjectsSub) The resulting object tuple ObjectsDiffObjectsDiffObjectsDiffObjectsDiffobjectsDiff is defined as the input tuple ObjectsObjectsObjectsObjectsobjects with all objects from ObjectsSubObjectsSubObjectsSubObjectsSubobjectsSub removed.

For a short description of the iconic objects that are available in HALCON see the introduction of chapter Object.

Attention

Image matrices and XLDs are not compared regarding their contents. Thus, two images or XLDs, respectively, are “equal” if they are located at the same place in the storage. By contrast, regions that are not located at the same place in the storage are compared regarding their actual contents.

Execution Information

• Supports objects on compute devices.
• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

obj_diffobj_diffObjDiffObjDiffObjDiff always returns 2 (H_MSG_TRUE).
