There is a really cool new tool out on the internet that can be used to help you vectorise any image. It produces really interesting and accurate results and is a lot better than the ones used by Illustrator. This new magical tool is called Vector Magic.
This online tool is designed to turn any inputted image into a vector image. Its very simple to use and the results can be retrieved off the server in under a couple of minutes. The engine works best with simple image with few colours. I've found that these result have come out the best. Photos which can also be upload, can be turned into vector but usually result in very jaggy edges between each of the paths.
There are only a couple of options to pick when uploading an image. Low, Medium and High. Low as the name suggests is done the quickest but produce the worst results. This isn't necessarily bad, if you want a quick starting point to work from. Medium and High do produce very accurate results. The high option usually results in hundreds of paths and shapes on your canvas. This can be useful if you want a very detailed image but is a pain if you want to edit your image afterwards.
Check it out see for yourself how it works. I'm sure you will be able to find a use for it. Vector Magic.
