28.循环语句for in

循环语句-for-in Python并没有提供类似C语言中那种传统意义上的for循环,而是提供了一种专门处理字符串,元组,列表,字典等可迭代的序列类型数据的增强型for循环。 遍历可迭代对象 使用for-in循环处理可迭代对象,可以使操作过程变的极其简单。 遍历字符串 s = "Hello Hogw ......

A Detector-Oblivious Multi-Arm Network for Keypoint Matching读书笔记

A Detector-Oblivious Multi-Arm Network for Keypoint Matching 背景:由于关键点检测器是在不同的损失函数下训练的,并且采用不同的算法设计的,因此它们通常对同一关键点坐标给出不同的描述(和置信度)。因此,每次与不同的关键点检测器组合时,都需要重 ......
