App for counting Kcals with the camera

I can make an application that can do this.

I have the concept and the idea to accomplish this task. We can take the photo of the food like eggs, ice cream, chips, drinks etc and by image recognition we can identify the food and we can enter the quantity of the food and we will have a database of the food already in the app and then we can calculate the calories, nutrition, protein the food. it's just a concept that can be done. Thanks. :)
