We have introduced a basic system for facial expression. If you are really interested in this topic, you may want to read this section for more guidance on how to improve the performance of the system. In this section, we will introduce you to compiling the
opencv_contrib module, the Kaggle facial expression dataset, and the k-cross validation approach. We will also give you some suggestions on how to get better feature extraction.
In this section, we will introduce the process for compiling
opencv_contrib in Linux-based systems. If you use Windows, you can use the Cmake GUI with the same options.
First, clone the
opencv repository to your local machine:
git clone https://github.com/Itseez/opencv.git ...
