can i replace an object in an image with another object?

edit

Yes it is

• You will first need an algorithm to detect your object. Without images or information on your end, this can be tons of different solutions, so give us something here.
• Then you need to extract the bounding box and perform some kind of object segmentation. CNN's seem to be doing quite well there.
• Then you need to adapt your template (new object) to the size of your bounding box
• Perform image merging with opacity to paste the new object into the image

Good luck!
