Removing an object in the foreground

[troutusa]

I have tried using Photoshop AI generative fill to remove the blue police car from the foregound.

I have tried to use Photoshop to remove the police car and use generative fill to complete the train and concrete barrier. Photoshop just puts in another car. I select the police car then tell photoshop to remove the car and extend the background.

I think maybe you're expecting a little too much here.

Normally, if you only want to remove something, it’s best to leave the Generative Fill field blank; Photoshop will assume you just want to fill it in. However, that’s also not working for me on this picture; like you said, it puts in a different vehicle in multiple variations, and the one without a vehicle looks bad. That indicates that Generative Fill probably wasn’t trained for this kind of very busy picture where the background is not typical. 

However, I got better results by painting with the Remove tool over the car. The Remove tool did what it says, as shown in the picture below. However, the result will still need some cleanup. It also looks like the tool AI wasn’t trained to recognize a train undercarriage, because although that part sort of fits in visually, it’s technically wrong. Maybe the decorative paint scheme on the locomotive is confusing the AI as to what the actual outline and shape of that object is, and it might not have recognized that it’s a train engine.

I think a major problem is that the area you want to replace is such a large proportion of the image, because the tool has to make more and more assumptions about what is behind it, and it doesn’t seem to be trained to make the correct guesses in this case.

See the demo below…It was possible to get better results by using the Object Selection tool to precisely select the car, and I Shift-dragged the Object Selection tool to also include the distracting shadows. I then painted with the Remove tool inside the selection, and that got pretty far. If the result of the Remove tool isn’t perfect, you can drag it again over the parts you don’t like and it will try again. After a few more passes with the Remove tool, it looks sort of all right…but still not totally realistic, again the AI doesn’t seem to know that is a train undercarriage. It has to completely guess what the bottom front of the train engine might look like, and it guesses wrong. It might be hard to do better than this with AI alone. If you want something that looks more believable, someone will need to research what the front of that locomotive actually looks like and manually paint it in.
