Augmented Reality, Mobile App Selfie Image Effect Elements Adding

We need to build a functionality exactly that it has in Facebook and Instagram. FB and Instagram has a functionality that is when you pick a selfie image of your face or picture from mobile then you can add some ear of animals like dog or elephant. You can add spectacles, Goggles or you can add a cap, crown jewelry etc on your face. Also when you pick a picture of your hands then some cool effects you can make there happening on your hands. Those all need to build up. We need to build that functionality in our one of the mobile app in Android and iOS. If you know how to do that then only you can apply here. If you think you need to do lot of research on this thing then please do not apply here. Do not waste your and our time please. Apply when you are confident to do that OR you did that before and you have that code saved in your drive. A little bit RnD is absolutely OK but if you think you need to do a lot of RnD then please do not apply here. We want a better pricing from you to build this functionality. Thank you.
