OpenCV嘴唇分割 [英] OpenCV Lip Segmentation
问题描述
一旦发现了嘴巴区域，人们通常如何提取嘴唇的形状(在我的案例中是使用haar级联)?我尝试了颜色分割和边缘/角落检测，但是对我来说它们是非常不准确的.我需要找到两个角以及中心处的上下唇.我听说过有关活动外观模型的信息，但是我在理解如何将其与python结合使用时遇到了麻烦，并且我没有足够的上下文来确定这是否是检测嘴唇不同部位的常规方法.这是我的最佳选择，还是我还有其他选择?如果我应该使用它，如何使用python和simplecv来开始使用它?
How do people usually extract the shape of the lips once the mouth region is found (in my case using haar cascade)? I tried color segmentation and edge/corner detection but they're very inaccurate for me. I need to find the two corners and the very upper and lower lip at the center. I've heard things about active appearance models but I'm having trouble understanding how to use this with python and I don't have enough context to figure out if this is even the conventional method for detecting different parts of the lips. Is that my best choice or do I have other options? If I should use it, how would I get started with it using python and simplecv?
推荐答案
以下是使用边缘检测和颜色分割进行嘴唇分割的两篇论文.试试看.
Here are two papers for lip segmentation using edge detection and color segmentation. Try them out.
