Yeah, I believe Seam Carving paper did this. Pretty simple, find the low-energy path and do linear interpolation between the two neighboring pixels (I think it also introduced some tricks to find n low-energy paths at once to avoid inserting into the same path again and again). But like the top comment pointed out. This algorithm is easy to implement and interesting, but in real-world examples are not better than salient object detection + cropping.
