What is the purpose of Gaussian blur?
The Gaussian blur is a way to apply a low-pass filter in skimage. It is often used to remove Gaussian (i. e., random) noise from the image. For other kinds of noise, e.g. “salt and pepper” or “static” noise, a median filter is typically used.
What is the advantage of using Gaussian blur?
Photographers and designers choose Gaussian functions for several purposes. If you take a photo in low light, and the resulting image has a lot of noise, Gaussian blur can mute that noise. If you want to lay text over an image, a Gaussian blur can soften the image so the text stands out more clearly.
Is Gaussian blur good?
The blur effect that may add artistic effect to your photo is a Gaussian blur. This effect on a photo is so helpful. It can reduce the noise and grain that are affecting your images. It could be very beneficial when overlaying an object to a photo that is too busy, or a lot is going on in the picture.
Why might we apply a Gaussian blur to an image before extracting features?
Gaussian blur the image to reduce the amount of noise and remove speckles within the image. It is important to remove the very high frequency components that exceed those associated with the gradient filter used, otherwise, these can cause false edges to be detected.
