Mobile app developer (C#)

Hello everyone, Hope you are doing well. Our client is looking for a team or a talented individual. Scope of the project : Want to develop Additional features in our app. Please check the details in the descriptions below. 1. Information about the app Compatibility: above iPhone X, iOS only Made by using : Unity / ARFoundation / ARkit / C# 2. How it works This app places guidelines on users' faces after turning on the camera so that users can easily draw self-portrait. and users can also study how the human face is structured through the anatomy filter. When the self-cam is turned on, a virtual guideline is placed on the face after recognizing the user's face. User takes a picture and saves it in the gallery. User sees the picture taken and draws the guideline on the drawing paper. Based on the guidelines drawn on the drawing paper, draw the eyes, nose, and mouth in the proper positions and complete the portrait. And later, if the user wants to study each part of the human face, can use the anatomy filter also. The above functions have already been made but What we want is to apply the same guidelines not only for self-portraits but also for already saved photos. What you'll do: You need to create a gallery feature. And apply AR effect to photos imported from gallery and download to gallery should be able to apply more than 2 filters to one scene (Mode 1,2 consists of 2 filters each) we have filters to apply, so you don't need to create a 3D model. Needs to be developed applicable to Android in the future. We plan to develop an Android app in the future, so please make it compatible. We tried to make this feature by using OpenCV, but failed because we are not opencv experts. Failed to merge multiple masks in the same scene. And we couldn't succeed in applying AR on an already saved photo. If there is an OpenCV expert or has another method, we want to solve the problem. Tips: For the introduction of the gallery function and the application of AR effects, I think it can be applied by using OpenCV, Dlib FaceLandmark Detector, or Firebase MLkit. Please apply if you have related knowledge, or if you can make a gallery feature in any other way. We have the opportunity to work together in any way! We will provide the prototype of the app and all the necessary details. If you have any questions you can ask us. Thank you,
