Very cool for simple images like the demo ones provided. But images with detailed content don't resize well and are much worse than a naive resize.

The basketball hoop is heavily distorted, as is the court, the squares on the building and the 3 point line.

That is explained in the section with the van Gogh painting. It is not like they are advertising the algorithm as a jack of all trades.

In this specific image there are even greater difficulties than in the Van Gogh painting: the unpainted wall portions on the left prevail over the "low energy" surfaces that surround them, and there are many rectilinear structures that demand very good preservation, like court lines, wall edges, iron bars, and worst of all the backboard, located in the middle of lower energy regions (the low contrast purple grid) that attract seams that bite off the corners of the backboard.

This image should look better with a strong penalty against seams that depart from vertical or horizontal lines, but it wouldn't be enough: the purple pillars and panels would be straighter but still squeezed.
