描述
prepare_deep_counting_modelprepare_deep_counting_modelPrepareDeepCountingModelPrepareDeepCountingModelPrepareDeepCountingModelprepare_deep_counting_model sets the templates of the objects that
should be counted by the Deep Counting model DeepCountingHandleDeepCountingHandleDeepCountingHandleDeepCountingHandledeepCountingHandledeep_counting_handle.
When applying the Deep Counting model using apply_deep_counting_modelapply_deep_counting_modelApplyDeepCountingModelApplyDeepCountingModelApplyDeepCountingModelapply_deep_counting_model,
objects in the search images that are similar to the provided templates
are detected and counted.
Note that this operator overwrites any previously set templates.
To also count scaled and rotated variants of the provided templates,
an automatic augmentation of the templates can be enabled by setting
the parameters 'angle_start'"angle_start""angle_start""angle_start""angle_start""angle_start", 'angle_end'"angle_end""angle_end""angle_end""angle_end""angle_end",
'angle_step'"angle_step""angle_step""angle_step""angle_step""angle_step", 'scale_min'"scale_min""scale_min""scale_min""scale_min""scale_min", 'scale_max'"scale_max""scale_max""scale_max""scale_max""scale_max", and
'scale_step'"scale_step""scale_step""scale_step""scale_step""scale_step" using create_deep_counting_modelcreate_deep_counting_modelCreateDeepCountingModelCreateDeepCountingModelCreateDeepCountingModelcreate_deep_counting_model or

When changing parameters of the Deep Counting model that influence the
template creation, prepare_deep_counting_modelprepare_deep_counting_modelPrepareDeepCountingModelPrepareDeepCountingModelPrepareDeepCountingModelprepare_deep_counting_model must be re-run
before apply_deep_counting_modelapply_deep_counting_modelApplyDeepCountingModelApplyDeepCountingModelApplyDeepCountingModelapply_deep_counting_model。The list of such parameters is provided in get_deep_counting_model_paramget_deep_counting_model_paramGetDeepCountingModelParamGetDeepCountingModelParamGetDeepCountingModelParamget_deep_counting_model_param。
注意
系统要求：要在 GPU 上运行此算子（参见 get_deep_counting_model_paramget_deep_counting_model_paramGetDeepCountingModelParamGetDeepCountingModelParamGetDeepCountingModelParamget_deep_counting_model_param），需安装 cuDNN 和 cuBLAS。更多详情请参阅 “安装指南” 中“深度学习及基于深度学习方法的要求”一章。此外，该算子也可在 CPU 上运行。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在内部数据级别上自动并行化。
此算子修改后续输入参数的状态：
在执行此算子时，若该参数值需在多个线程间使用，则必须对其访问进行同步。
