Apologies for not attaching the photo in question, don't wish it to be published in open.
Imagine a person in gray clothes sitting on a dark chair against a relatively light background. A piece of the chair is showing from above one shoulder. What would be the most efficient way to remove that piece from the photo using Photoshop?
In the past I used the Clone Stamp Tool to manually patch that odd part with the color of the surroundings. It worked fine but was manual labor. I wonder if there is an automatic intelligent algorithm in Photoshop to do just that? Those objects in the photo are more or less evenly colored, with sufficient contrast between them, that should hopefully make the job easier.
The idea of the photo layout is below in a sample drawing:
