Image facial functions loaded with Javascript

I want to make an online application where the user can upload an image of himself and the application will provide hime with some statistics for his facial features so he can find how the user's celebrity is the same. I don't want to use OpenCV, for example, because my client server doesn't support that. I would like to do this with Javascript. For example, I would like something like this, but with image loading: Example_1 or is this exactly what I want to do: Example_2 . Is there a way to do what I want with Javascript only, and if there are other ways, feel free to tell me about them. Thanks for the help.
