然后他们用一个自己设计的算法来处理这些视频,并让算法知道每个手势的意义。
The idea was that the algorithm would learn the association and, having seen the samegesture performed by different people,
他们的设想是,该算法会记住每个手势所对应的意义,而在对不同人摆出的相同手势进行处理后能够概括出手势本身的意义,
would be able to generalise what was going on and thus recognise gestures performed bystrangers.
从而识别任何人摆出的手势。
Unfortunately, it did not quite work out like that.
很遗憾,实际与预想的不太一样。
In much the same way that spoken language is actually a continuous stream of sound,
其实指挥飞行员所用的手语和人说的话差不多。
so the language of gestures to pilots is also continuous, with one flowing seamlessly intothe next.
后者实际上是一串连续的声音,而手语同样也是连续的,因为两个动作之间是连贯的。
And the algorithm could not cope with that.
但该算法无法处理这种连续的信息。
To overcome this difficulty Mr Song imposed gaps by chopping the videos up intothree-second blocks.
