What is the Laplacian operator used for?

It is a second-derivative operator used to highlight regions of rapid intensity change, making it ideal for edge detection and image sharpening.

Can I adjust the strength of the effect?

Yes, you can use the Intensity slider to control the strength of the Laplacian effect from 0.1 to 5.0.

What does the Threshold setting do?

The threshold determines the sensitivity of edge detection; values between 0 and 255 filter out noise to isolate significant edges.

Which file formats are supported?

The tool supports common image formats including JPEG, PNG, WebP, GIF, BMP, and TIFF.

Can I apply the filter multiple times?

Yes, you can set the Iterations parameter to apply the Laplacian operator up to 3 times for a more pronounced effect.
