What does edge smoothing mean?

Edge Smoothing. Smooths jagged edges in low-resolution images such as screen captures or images from the Web. Finest Detail. Sharpens edges on vector-based data including text, graphics, and line art. (This setting does not affect photographs.)

Which filter preserves edges in a better way?

From the results, it has been noticed that the neutrosophic-based Wiener filter is able to suppress noise and preserve edges.

Why is smoothing important in edge detection?

Basically to avoid noise affecting detection. "Because these kernels are approximating a second derivative measurement on the image, they are very sensitive to noise. To counter this, the image is often Gaussian smoothed before applying the Laplacian filter."

What is meant by image smoothing?

Image smoothing is a digital image processing technique that reduces and suppresses image noises. In the spatial domain, neighborhood averaging can generally be used to achieve the purpose of smoothing. Commonly seen smoothing filters include average smoothing, Gaussian smoothing, and adaptive smoothing.
