参考 IBUG 上的格式

你好,我按照格式设置好了数据库,训练集有200张图片,测试图片的错误率有0.34,而且stage4比stage3的错误率还要高。是我数据库设置出了问题吗

@vinccccho 训练数据太少了,另外注意下数据的准确性

run函数里面有对landmark值的读取,而且根据这些值和bbox计算得到了roi,请问咋样测试自己的无landmark值得图片呢?

@532741697 用 OpenCV 检脸得到框之后再做标点

你好,我已经训练了一个模型,眼睛,眉毛和鼻子都没问题,可是嘴巴不能张开,什么原因呢?我是用prepare准备数据(以opencv提取bbox),test也用opencv提取bbox,就是不能张大嘴,不知道那里出错了。

@simon5u 还是训练数据的问题,可以尝试不用 opencv 取框,因为这样做会导致很多脸被筛掉。可以考虑的策略是按某种规则根据 68 个点来选取框,然后做训练,最后应用模型时将前面检测器的框做调整。
