描述

算子 gen_empty_objgen_empty_objGenEmptyObjGenEmptyObjGenEmptyObjgen_empty_obj creates an empty tuple. This means that the output parameter does not contain any objects. Thus, the operator count_objcount_objCountObjCountObjCountObjcount_obj returns 0. However, clear_objclear_objClearObjClearObjClearObjclear_obj can be called for the output. It should be noted that no objects must not be confused with an empty region. In case of an empty region, i.e. a region with 0 pixels count_objcount_objCountObjCountObjCountObjcount_obj returns the value 1.

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