The Wiener filter can be used in image processing to remove noise from a picture.

This is ideal for removing noise but also indiscriminately blurs edges too.

Hence the edges can be preserved while removing noise from the image.

Active logic gates may be integrated in large numbers because each gate tends to remove noise at its input.

Video denoising is the process of removing noise from a video signal.

A noise gate does not remove noise from the signal.

Noise reduction is the process of removing noise from a signal.

Another approach for removing noise is based on non-local averaging of all the pixels in an image.

The video was processed to remove random noise and camera shake without destroying historical legitimacy.

This filter is used to "smooth" the display by removing noise from the envelope.
