| 英文摘要 | in this paper, two dimensional principal components of natural images (2d-pcs) are proposed. similar to principal components of natural images (1d-pcs), 2d-pcs can also be viewed as fundamental components of human's receptive field because they contain edge-like, bar-like and grating-like patterns. however, compared to 1d-pcs, 2d-pcs are of surprising symmetry, stable regularity, good interpretability, and have little computational complexity in real applications. then, based on 1d-pcs and 2d-pcs, we design two kinds of statistical texture features (stf(1d) and stf(2d)), and apply them to multi-class facial expression recognition. numerous experimental results demonstrate that our statistical texture features are better or not worse than other popular features for facial expression recognition.
