在苹果公司上周发布的iOS 10和 macOS Sierra系统中，它们为系统中的“照片”应用增加了自动识别功能。如今有一家名为Reddit的网站发现了这个功能背后的秘密。

　　有人在macOS照片应用中发现了几行代码，这里显示了目前iOS 10和macOS Sierra可以识别的物品和面部表情的种类。我们不太确定这是不是所有，不过确实有人将这几千个单词全列出来了。

　　当照片应用首次开启后，会对用户照片库进行扫描，它能分析出贪婪，厌恶，中性，尖叫，微笑，惊喜和可疑等七种面部表情，以及4432种物品类别或场景，之后用于“回忆”给你(将照片按某一类别制成段视频)。我们猜也会用于Siri的搜索，但目前不是很确定。

　　更难的是图像分析识别技术，而不是装进去多少个单词。不过你有兴趣的话，倒是可以看看这四千多单词认识多少……
