is there any better way to get a military mimetic texture than using svg filter effects?

here the svg code as example:
…

 <svg xmlns="http://www.w3.org/2000/svg">
  <filter id="a">
    <feTurbulence type="fractalNoise" baseFrequency=".02" numOctaves="3" />
    <feComponentTransfer>
      <feFuncR type="discrete" tableValues="0 0 1" />
      <feFuncG type="discrete" tableValues="0 0 0 1 1" />
      <feFuncB type="discrete" tableValues="0 1" />
    </feComponentTransfer>
    <feColorMatrix values="1 0 0 0 0 
                           -1 1 0 0 0 
                           -1 -1 1 0 0 
                           0 0 0 0 1" />
    <feColorMatrix values="-.08 .42 .09 0 .08 
                           -.17 .35 -.08 0 .17 
                           -.08 .15 -.04 0 .08 
                           0 0 0 0 1" />
  </filter>
  <rect width="100%" height="100%" filter="url(#a)" />
</svg>
