After being absent for a week, I have finally reappeared! Without further ado, let me introduce PhotoWipe. As the title suggests, this is really a great little tool. The place where I can imagine it delivering its maximum value right now is for removing mosaics (in fact, there are already people using it for that purpose). The comparison chart from earlier clearly shows its effects. Although it cannot perfectly remove obstacles, it does at least make them transparent. For those who don't know how to use Photoshop, PhotoWipe is undoubtedly a good choice. Of course, you shouldn't expect it to be perfect because the results largely depend on your own operations. You need to use your mouse to draw out the parts that need to be removed. If your micro-operations aren't good, you might accidentally erase parts that you didn't intend to remove!
