halcon局部阈值分割算法实现详解算法概述接口解析local_threshold()函数halcon中的local_threshold()算子，用于基于局部阈值分割图像。接口定义如下：local_threshold(Image : Region : Method, LightDark, GenParamName, GenParamValue : )方法选择当前只支持adapted_std_deviation方法，通过局部mask_size*mask_...

内存消耗:ThreadLocal为每个线程创建变量副本,这意味着当线程数量较多时,会占用较多的内存资源。特别是在长时间运行的系统中,如果线程频繁创建和销毁,可能会导致内存泄漏问题。 数据共享限制:由于ThreadLocal变量是线程私有的,因此无法直接实现线程间的数据共享。如果需要在线程间传递数据,可能需要借助其他机制(如消息队列、...
