名称

get_ncc_model_originT_get_ncc_model_originGetNccModelOriginGetNccModelOriginget_ncc_model_origin — 返回 NCC 模型的原点（参考点）。

签名

get_ncc_model_origin( : : ModelID : Row, Column)

描述

算子 get_ncc_model_originget_ncc_model_originGetNccModelOriginGetNccModelOriginGetNccModelOriginget_ncc_model_origin returns the origin (reference point) of the NCC model ModelIDModelIDModelIDModelIDmodelIDmodel_id. The origin is specified relative to the center of gravity of the domain (region) of the image that was used to create the NCC model with create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelCreateNccModelcreate_ncc_model。Hence, an origin of (0,0) means that the center of gravity of the domain of the model image is used as the origin. An origin of (-20,-40) means that the origin lies to the upper left of the center of gravity.
