QUESTION
Im using dlib's hog detector because it finds faces much better than opencv haarcascades. But it can not detect emotions on faces (or can???). I need extract a "sub-image" from dlib::rectangle with face, and create cv::Mat from it to call cv::detectMultiScale() with preloaded "haarcascade_smile.xml".
How to perform this extraction/conversion?
Code sample below...
...ANSWER
Answered 2019-Aug-24 at 13:09There are two ways you can achieve this, either through the extract_image_chips
functionality in dlib (docs) or by extracting the sub-image from a wrapping cv::Mat
using the corresponding OpenCV API. Which one you will use depends on how convenient the choice is for the rest of your processing pipeline.
Concluding from your sample it seems that the OpenCV path is the most convenient (but again, please review the design and API options):
