Q1: Are you trying to change one image or several?

Some.

Q2: What image libraries are you going to use?

This is my question that I should use.

Q3: Do you want a fully automated process or a semi-manual in order?

I will mark the area on a scale, and then select an object of my choice from the list, one image at a time.

Q4: What parameters do you want to specify?

The dimensions of the selected area of ​​the face and the object to be inserted (for example, orange in this example) -

Q5: Do you know face recognition algorithms?

I believe that I do not need recognition algorithms, because I select the area on the face manually. All I need to do is change the selected area as shown in the sample. -

Answer 1

I think the obvious answer to using Adobe Photoshop is out of the question?
