Pick up your mobile phone and take photos.

You can use PicsArtAPP, taking matting as an example:

1. First, start picsart on the mobile phone and open a picture of the character material.

2. Select the silhouette tool from below, enter the silhouette interface, and click the villain logo below.

3. Then it will automatically cut the picture, click on the eyes to close it, thus hiding the background.

4. Then choose the eraser tool, adjust the relevant parameters, and erase the redundant parts around to make the transition more natural.

5. Then click Save in the upper right corner to save the picture to the picture library.

6. Then open another background picture and click the "Add Photo" option below to add the picture you just selected.

7. Adjust the size and position, click the checkmark in the upper right corner to confirm and save.
