论文《Extended Supervised Descent Method for Robust Face Alignment》对SDM方法做了扩展，使程序更鲁棒。

论文主要在三方面做了Improments,分别是：
Adaptive Feature Block
在初始的SDM方法中，我们使用fixed-size blocks去提取SIFT特征进而预测shape。但实际上，从直观上来看，the feature extraction block size与the value of shape increment有很大关系。当shape increment比较大时，我们应该提取较大块的SIFT特征，这样就可以获取更多有用继续阅读 »
tbox provides a lightweight implementation of stackless coroutines
and it's interfaces are very simple too, for example:
c
tb_lo_coroutine_enter(coroutine)
{
while (1)
{
tb_lo_coroutine_yield();
}
}
The switch performance of this stackless coroutines is faster than the implementation of tbox's继续阅读 »
Sublime Text is an extremely powerful text editor. Currently I use Sublime Text 3 and quite enjoy its simplicity and extensibility. In this blog, I would like to introduce some of my favorite packages that leverage my productivity.继续阅读 »
