In my last blog I said I tried using smiledetect.cpp to detect smiles, and it worked just great. smiledetect.cpp puts a rectangle on the left side of the video output screen, with the height denoting how closely the smile hit resembles the smile in the video. The only change I made to the code so far was the addition of code for capturing video output.
I'd like to continue working in Python on this project; it's the first time I've ever worked with Python, so this is an educational experience for me. However, I have a lot of C/C++ experience, so it's tempting to flesh out the C++ code I already have and create a finished program for detecting emotions that way.
