linkBlur filters

This filters has the ability to blur or smooth an image, reducing the image noise and the definition of each detail

linkBox Blur

w=1/9(111111111)w = 1/9 \begin{pmatrix} 1 & 1 & 1 \\ 1 & 1 & 1 \\ 1 & 1 & 1 \end{pmatrix}1

Here you can see the filter applied to an image, and check how the image is transformed.

And here the filter applied to a video.

On the video the blur function works amazing, but on the image we can see duplicated parts of the image.

linkGaussian Blur 3x3

w=1/16(121242121)w = 1/16 \begin{pmatrix} 1 & 2 & 1 \\ 2 & 4 & 2 \\ 1 & 2 & 1 \end{pmatrix}1

Here you can see the filter applied to an image, and check how the image is transformed.

And here the filter applied to a video.

As we can see with this new matrix the blur is applied to the image, but we cannot detect annoying duplicated sections.

linkGaussian Blur 5x5

w=1/256(1464141624164624362464162416414641)w = 1/256 \begin{pmatrix} 1 & 4 & 6 & 4 & 1 \\ 4 & 16 & 24 & 16 & 4 \\ 6 & 24 & 36 & 24 & 6 \\ 4 & 16 & 24 & 16 & 4 \\ 1 & 4 & 6 & 4 & 1 \end{pmatrix}1

Here you can see the filter applied to an image, and check how the image is transformed.

And here the filter applied to a video.

With the increase of the size of the kernel we can create bigger blurs that perform incredibly well on images and videos.
