I can provide you with a quality solution for this project as I have good experience and grip on the tools needed for the job, such as: OpenCV or dLib. I have developed many applications that involve face detection, face-landmark detection, smile estimation, age prediction, image segmentation, video manipulation (zooming, panning, etc.). I can share my work with you, upon request. You can also refer to the reviews section on my profile to see how many other satisfied customers have rated my work.
We can further discuss the budget and requirements in detail to find a solution that suits you.
Regards,
RAS.
