A new method of incorporating corner information for mouth feature extraction is proposed.
提出了利用角点信息提取嘴唇特征的方法。
Among the many image features, not only do the corners have the least amount of data, but also they are quite stable, which makes corner detection as an important branch of feature extraction.
在众多图像特征中，角点不仅具有最少的数据量，而且稳定性极高，这使角点检测成为特征提取的重要分支。
