CNN in combination with KNN

Please where you able to achieve this? I am working on a project that really need this and it is urgent.

Hello, I have same problem with my model. I am
running a project using Dental X- ray to find age from the images and back to knowledge of pervious research I found it that If use hybrid CNN- KNN it might help me to come up with higher accuracy. May I have your suggestion?
The result of the CNN from the images it will be so similar and that’s the point made me to decide use KNN after CNN.
