The stitchTiles attribute defines how the Perlin Noise tiles behave at the border.
You can use this attribute with the following SVG elements:
<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
<filter id="noise1" x="0" y="0" width="100%" height="100%">
<feTurbulence baseFrequency="0.025" stitchTiles="noStitch" />
</filter>
<filter id="noise2" x="0" y="0" width="100%" height="100%">
<feTurbulence baseFrequency="0.025" stitchTiles="stitch" />
</filter>
<rect x="0" y="0" width="100" height="100" filter="url(#noise1)" />
<rect x="100" y="0" width="100" height="100" filter="url(#noise1)" />
<rect x="0" y="100" width="100" height="100" filter="url(#noise1)" />
<rect x="100" y="100" width="100" height="100" filter="url(#noise1)" />
<rect x="220" y="0" width="100" height="100" filter="url(#noise2)" />
<rect x="320" y="0" width="100" height="100" filter="url(#noise2)" />
<rect x="220" y="100" width="100" height="100" filter="url(#noise2)" />

noStitchThis value indicates that no attempt is made to achieve smooth transitions at the border of tiles which contain a turbulence function. Sometimes the result will show clear discontinuities at the tile borders.
stitchThis value indicates that the user agent will automatically adjust the x and y values of the base frequency such that the <feTurbulence> node's width and height (i.e., the width and height of the current subregion) contain an integral number of the tile width and height for the first octave.
