Apple, Google, and Samsung are competing on a number of fronts—from telephones, to well being apps, to smartwatches—and that rivalry extends to AI instruments as effectively. All of those tech giants supply AI-powered object removing options of their cell picture modifying apps, which ostensibly enable you do away with an undesirable individual, a tree, a hand, or the rest that is ruining your shot, with solely a faucet or two on the display screen.
Nevertheless, simply because Apple, Google, and Samsung all supply AI object removing doesn’t suggest the instruments are of the identical customary. There’s been a good bit of chatter on-line about how these options stack up in opposition to each other, so it feels as if a head-to-head object removing check is so as.
These AI instruments all work in the identical manner. Clearly, the instruments do not know what’s actually behind the thing being eliminated—however due to a mix of clues within the surrounding pixels and the picture coaching constructed into their underlying fashions, they will make a fairly good guess. How good that guess is then determines the standard of the tip outcome.
This check covers three instruments: Clear Up (in Apple Pictures on iOS), Magic Eraser (in Google Pictures on Android), and Object Eraser (within the Samsung Gallery app on One UI). These instruments all seem as choices once you open pictures within the related apps. For testing functions, I’ve borrowed some nice pictures from Taan Huyn, Tolga Ahmetler, and Marek Piwnicki.
(A fast notice on the comparability pictures: There’s some variation in decision due to how I saved them utilizing numerous units; it has nothing to do with the AI instruments in query, so you may principally ignore the sharpness of the images.)

Our first picture problem—eradicating the lamp within the picture above—is comparatively easy in some methods, however advanced in others. There are some helpful pointers for the AI by way of the wall and the window, however there are additionally shadows to cope with (together with the shadow of the lamp on the wall behind it, which AI is not good sufficient to realize it must take away as effectively).
First up was Apple Clear Up. The software did a positive job of figuring out the lamp as I scribbled over it—I just like the glow impact—and as soon as the removing course of was full, the again wall was crammed in properly. Many of the window pane work regarded okay too, however there have been a number of bizarre artifacts left as proof of an object removing.
Subsequent was Google Magic Eraser. The lamp wasn’t recognized as a suggestion for one thing to erase, however choosing it was fairly easy and correct by way of the boundaries. Sadly, whereas a lot of the job was completed effectively, Magic Eraser left proof of the lampshade up on the high, like a ghost of what had been there earlier than.
Lastly, I attempted Samsung Object Eraser. Right here the thing choice course of was a bit extra fiddly—it is harder to zoom and pan in Samsung Gallery, and the automated choice was much less correct. Nevertheless, the removing job was the perfect of the three, with each the wall and the home windows precisely crammed in.

Our second picture problem is eradicating the strolling man from this road scene, and it is a difficult one—the AI has to think about a lot of the white automobile behind our main topic, in addition to fill within the street and its markings. What’s extra, it is a darker scene, with the foreground in focus and the background getting more and more blurry.
With Apple Clear Up, the software’s computerized choice wished to clear away the automobiles within the background quite than the person within the foreground, however choosing him was simple sufficient. The AI fill outcomes had been patchy, and acquired worse additional again within the scene, with the automobile on the again turning right into a pixelated mess.
Over to Google Magic Eraser, which additionally wished to erase individuals within the background quite than the foreground. It had some hassle choosing out the person in opposition to the darkish and moist road—and it then had issue each eradicating the entire man and changing the pixels correctly. It borrowed pixels from the unsuitable a part of the picture on the entire, and the software could not even keep it up the yellow line persistently.
As for Samsung Object Eraser, once more the choice course of was a bit awkward, however in the end it did an ideal job of choosing the male determine in opposition to the background. It then did very well at removing: It was the one AI to really find yourself with a practical wanting automobile and street after the person had gone. Whereas it is not good, this might most likely idiot most individuals at first look.

This third picture problem, eradicating the bicycle from this scene, presents a number of info for the AI to make use of by way of the encircling discipline. The hardly seen fencing behind the bike provides to the problem, so I used to be to see if these instruments would attempt to proceed the fence, or simply ignore it and go along with the grass.
With this one, Apple Clear Up wanted a number of goes to get the entire of the bicycle chosen—presumably as a result of it does not look like one single object. When that was completed, Clear Up was moderately proficient at filling within the blanks, although each the greenery and the fence it created confirmed inconsistencies.
Google Magic Eraser additionally wanted a number of makes an attempt to get everything of the bike chosen. It tried to fill within the fence in addition to the sphere, and whereas the outcomes weren’t a catastrophe, there have been apparent errors—among the bike wheel spokes are nonetheless there, for instance. It was perhaps barely higher than Apple Clear Up, however not by a lot.
As with the person on the street, Samsung Object Eraser was the perfect at making an correct choice first time round, and higher at placing one thing convincing within the area that was left. Each the sphere and the fence had been crammed in an correct, lifelike manner, and this might simply go as an unedited picture.

The very first thing to say is that your mileage might range with these types of duties—as you’ll see in case you take a look at related comparability challenges from round social media and the web at massive. Each picture has completely different traits, and each AI software has its personal method in coping with object removing.
By way of my assessments, Galaxy AI and Samsung’s Object Eraser are the clear winners. The software appears to take extra time over the substitute pixels, and does some precise picture technology quite than simply copying and pasting pixels from elsewhere within the picture—as you may see with the automobile on the road. That is simply an AI imagining of a automobile, not the precise automobile, nevertheless it makes for a photograph that appears real.
Apple and Google did okay, and had been about on a par with each other. The alternatives are simple to make (simpler than with the Samsung, really), and a few extra easy removing duties are dealt with completely effectively. Nevertheless, these AI removing options do are likely to wrestle with advanced operations the place there are fewer clues about how the background ought to look.
In the end, it is unlikely that anybody’s going to alter their cellphone solely due to the AI object removing instruments it presents, nevertheless it’s fascinating to chart the progress these three firms have made with their AI choices. It is also price noting that Google Pictures and its Magic Eraser can be found on all Android and iOS units, which places stress on Apple and Samsung to maintain up (or keep forward).
