一鍵消除照片裡的路人與雜物：AI 去除工具怎麼用

The Perfect Landscape, Ruined by a Passerby

You've waited for a long time at a scenic spot and finally taken a beautiful photo, but when you get home and look at it, you notice a stranger in the background, a trash can on the ground, and power lines in the sky. In the past, you would have had to use Photoshop to painstakingly edit out these unwanted elements, often leaving behind noticeable traces. Now, with AI, you can simply draw a box around the offending object, click, and it will magically disappear, with the background seamlessly filled in.

How AI Removal Works

All you need to do is "circle" the unwanted object, and the AI will perform two tasks: remove it and "imagine" what the area would have looked like if it hadn't been obstructed, then automatically fill it in. Because the AI has seen a vast number of photos, it knows what grass, sky, and walls should look like, allowing it to fill in the area naturally, making it almost impossible to tell that the photo has been edited.

What Can Be Removed

• Passersby: strangers in landscapes or selfies.
• Clutter: trash cans, power lines, signs, and other objects on the ground.
• Blemishes: skin imperfections, wall stains.
• Watermarks and text (note: do not use this feature to remove others' copyright watermarks).

Mainstream Tools

• Simple, free, and easy to use: Cleanup.pictures — just draw a box around the object and it's gone, all on the web.
• Background removal and object removal, product photos: PhotoRoom, Pixelcut.
• Mobile photo editing apps with built-in removal: most AI photo editing apps have this feature.

Tips for Using it Well

1. Draw the box carefully: the closer the box is to the object, the more natural the fill-in will be.
2. Remove large objects in stages: if the object is too large, it may not be filled in correctly, so remove it in stages.
3. Check complex backgrounds carefully: the simpler the background (sky, grass), the better it will be filled in; complex patterns require closer inspection.
4. Make adjustments if necessary: if the fill-in doesn't look right, draw the box again or try a different tool.

A Moral Reminder

AI removal is very convenient, but do not use it to remove watermarks or signatures from others' work — that is a copyright infringement. Removing clutter from your own photos is fine, but tampering with others' creations is not.

TheAI Academy Summary and Review

To be honest, "removing passersby" is probably the most useful and commonly used feature in AI photo editing. A photo that would have been deleted because of a stranger in the background can be transformed into a beautiful, shareable photo in an instant.

It's not perfect — if the background is too complex, the fill-in may not be seamless, and that's when you need to rely on your own eyes. But for everyday photos that are "almost perfect except for that one stranger," it's a lifesaver. Try taking a photo that's been ruined by a passerby and uploading it to Cleanup.

In a nutshell: removing passersby is the most impressive feature in AI photo editing — but it's not foolproof, especially with complex backgrounds, so the final check still relies on your eyes.
