obj_diff
— Calculate the difference of two object tuples.
obj_diff(Objects, ObjectsSub : ObjectsDiff : : )
obj_diff
calculates the set-theoretic difference of
two object tuples:
(objects in Objects) - (objects in ObjectsSub)
The resulting object tuple ObjectsDiff
is defined as the input tuple
Objects
with all objects from ObjectsSub
removed.
For a short description of the iconic objects that are available in HALCON see the introduction of chapter Object.
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.
Objects
(input_object) object(-array) →
object
Object tuple 1.
ObjectsSub
(input_object) object(-array) →
object
Object tuple 2.
ObjectsDiff
(output_object) object(-array) →
object
Objects from Objects
that are not part of
ObjectsSub
.
obj_diff
always returns 2 (H_MSG_TRUE).
