How do I find call out bubbles in an image?

Hi I have an image that has call out bubbles in it (call out = comic book text bubbles - i didn't know they were called that). I need to find where each of these are in a given image and get the location and size of each of these. Thanks!!\

AS3, Flex, Bitmap

That's a tough one actually. You want to do shape recognition with variable shapes ? You've probably seen the FlashSURF lib... It's pretty complex already but it obviously recognises predefined markers. If you read through Eugene's blog you will probably find some interesting pieces for what you need (edge detection specially).

A quick fix could be to preprocess/simplify the image a bit in order to contrast the bubble more against the rest and after check for abnormally big areas with a certain colour (if you're lucky enough to have the same colour for all the bubbles). There's a pretty handy in-built method with the BitmapData object called getColorBoundsRect(), it won't find your bubbles out-of-the-box but with some tweaks it could do the trick (I've used it for similar ends)
