接口设计感觉不太好用

我看了下例子，上层应用还需要去操作cuda等原始接口，这相当不好。

非常感谢你的关注和提议，考虑到易用性和简洁性，我们会尽快开发出部分高层借口，在视频和静态图片中均可使用。 颜色空间变换二值化的例子已经更新为高层API. Thank you very much for your attention and suggestions. Considering the usability and simplicity, we will develop some high-level excuses as soon as possible, which can be used in both videos and images. colorSpace and binarization samples has been updated.
