I have some old photographs that I have scanned. While the image of the person is clear, the background has several blurs and is not a perfect black as one would desire.
Is there a way to detect the person's image alone as a separate object, thereby isolating it from the background? That way, I could get rid of all background noise. What is the technical jargon for this process? I searched for 'Object detection', but that leads me to engineering papers! Could someone point me to useful videos using Lightroom in this regard?
