Frequently Asked Questions

What is edge detection?

Edge detection identifies points in an image where brightness changes sharply. The Sobel operator used in this tool calculates the gradient of image intensity at each pixel, highlighting edges and contours.

What is the Sobel operator?

The Sobel operator performs 2D spatial gradient convolution on images. It uses 3x3 kernels to approximate the derivative in horizontal and vertical directions, combining them to find edge magnitude and direction.

Can I adjust the detection sensitivity?

Yes! Use the "Edge Intensity" slider to control how sensitive the detection is. Higher values amplify weaker edges, while lower values only show strong edges.

Is this tool free?

Yes, completely free! No registration required, all processing happens in your browser locally.
