Image cutout completed in 3 seconds! Mechanism of AI background removal tool and pro-level usage techniques

"Cutout" is no longer a human job.

Whiting out product images, placing people on presentation materials, creating YouTube thumbnails... In design work, the task of "erasing (cutting out) image background" is unavoidable.

In the past, it was necessary to use Photoshop's "Pen Tool" and trace the outline steadily like a craftsman. It was not uncommon for it to take tens of minutes to cut out each strand of hair.

However, now is the era of AI (Artificial Intelligence). Work that once required skilled techniques now finishes in one drag and drop, just a few seconds. Moreover, its accuracy may even be more precise than human manual work.

This time, we explain the mechanism of AI background removal tool, usage techniques to accelerate business and creative, and the backstory of "why it can be used for free".

Image Background RemoverRemove image background automatically using AI

How does AI erase the background?

Have you ever wondered "Why can it distinguish between humans and background?"? AI technology called "Semantic Segmentation" is used for this.

Recognition: AI understands objects in the image as "This is a person", "This is a dog", "This is a car".
Separation: Specify the boundary line between "Person (Foreground)" and "Others (Background)" in pixel units.
Deletion: Replace pixels in the background part with transparent (alpha channel).

Since recent AI models have learned with millions of images, "Hair fluttering in the wind" "Through lace curtains" "Zebra in complex background" Even with such super high difficulty images, it can cut out surprisingly cleanly.

3 Major Benefits of Background Removal Tool

1. Overwhelming "Time Saving"

Let's think about product registration on EC site as an example. If you register images of 50 products a day, if it takes 10 minutes per image manually, it takes about 8 hours (a full day!). However, with AI tool, it takes 5 seconds per image. Even with 50 images, it is only 4 minutes. You can use the saved 7 hours and 56 minutes for "work that only humans can do" such as product planning and marketing.

2. No Special Software Required (Zero Cost)

There is no need to subscribe to expensive professional software like Photoshop (thousands of yen per month). If you have a Web browser, you can work anytime, anywhere, on Windows, Mac, smartphone, or tablet.

3. Uniformity of Quality

With manual work, variations such as "Mr. A is polite but slow" and "Mr. B is fast but sloppy" appear. With AI, anyone can finish with consistently high quality.

Techniques by Usage Scene

EC / Flea Market Apps (Mercari / Amazon)

Make products stand out: Just making the background pure white (#FFFFFF) makes the charm of the product stand out and gives a sense of cleanliness. White background may be mandatory on platforms such as Amazon.
Composite Photo: If you cut out the product and combine it with a background image of a stylish cafe, you can create an image photo without incurring shooting costs.

YouTube / SNS

Thumbnail: Cut out your surprised face and place it large. "Text + Cutout Image" is a standard composition to increase click rate.
Icon: Instead of cutting out your photo roundly, making the background transparent and then blending it into the design makes it a professional icon.

Material Creation / Presentation

Logo Transparency: The background of the company logo image is white and does not match the background color of the slide... Solved in one shot at such times.
Person Placement: In the member introduction slide, erasing the background and arranging only the upper body gives a sense of unity and makes a sophisticated impression.

Frequently Asked Questions (FAQ)

Q. The background became black when downloaded.

A. That may be the specification of "Viewer (Display Software)". Many image viewing software display transparent parts in black or white. Please try pasting it to PowerPoint or editing software. It should be properly transparent.

Q. Which file format should I save?

A. Please be sure to choose PNG (Ping) format. Since JPG (Jpeg) cannot hold transparent information, transparent parts are painted white arbitrarily.

Q. Photos that cutout does not go well?

A. Photos where "subject and background colors are similar (white clothes on white wall)", "subject is out of focus", or "too dark" are not good. The trick is to wear clothes of a different color from the background in a bright place when shooting.
