I'm trying to find if a new object has been added to a scene. The initial scene would most likely be lacking any kind of objects but might contain some patterns. The image for the scene containing the new object could also be taken from farther distance.

Would feature detection be a good option to achieve this? Or maybe something else? I'm basically looking for pointers to what I should start reading about.

This is how the two scenes might be Initial scenne Scene with object

Well, if the camera is not moved within the two shots you could subtract the two images from each other which will give you what has changed. Now that you know what has changed you can apply something like object detection to the scene.

@JAyThaRevo The camera does move. The images could be taken at a farther or nearer distance like the images that I've posted.
