Why median filter is not suitable for Gaussian noise?
The median filter is sometimes not as subjectively good at dealing with large amounts of Gaussian noise as the mean filter. in which the noise has been entirely eliminated with almost no degradation to the underlying image.
How median filtering is used to reduce image noise?
It is very effective at removing impulse noise, the “salt and pepper” noise, in the image. The principle of the median filter is to replace the gray level of each pixel by the median of the gray levels in a neighborhood of the pixels, instead of using the average operation.
Which filter is used to remove noise?
You can use linear filtering to remove certain types of noise. Certain filters, such as averaging or Gaussian filters, are appropriate for this purpose. For example, an averaging filter is useful for removing grain noise from a photograph.
Which is more effective in impulse noise reduction mean or median filter?
The median filtering is efficient for reducing the impulse noise.
