Surfing Footage Effects

Hi,
I'm trying to apply filters to footage of surfing to make some really cool-looking surfing videos. One of the things I'm trying to do is take video of a surfer, color the surfer and his board all white, and color everything else black. I have tried a number of methods.
Vectorize Color Filter in FCP6 gets close but does not give me proper outline of the surfer and board
Magic wand in Photoshop frame-by-frame takes way too long and hand-painting is not consistent enough
I cannot get the Track Motion feature in After Effects or Motion to apply an effect to the moving object. I can track the motion of the surfer in After Effects and Motion, but I cannot apply any effect to the motion track nor to the exact shape of the surfer and his board
Please help! I will send stills of what I am talking about. I am making a next-generation surf video and have spent tons and tons of hours researching and still cannot find the solution. This post is a last-ditch effort. Any help with this effect or cool unusual ideas that might work with surf footage would be very much appreciated, thanks
Matthew

There's a couple of ways to approach this, here's one;
you'll key out the ocean and create a matte. once the matte is created you can apply effects to one side without affecting the other. you may need to take a couple of passes at it but this is what we do =)

What exactly do you mean by key out the ocean and create a matte? I have been working with the 8-point matte but it is almost impossible to get the matte perfectly around the surfer. Thanks so much for replying, I really appreciate the help :)

thats another way to approach it, by rotoscoping. yes you would need more points, use the pen tool to create your shapes.
I would break up the rotoing to the major shapes of the body. torso, right upper arm, right fore arm, left upper arm..etc..(so a dedicated animated mask per part) and keyframe every 5 or 10 frames.
It's hard to tell what would be the best path to go without seeing the footage.
There may be a filter that can do what your describing. But I believe these two ways would give you the most control over what you want the surfer or the ocean to look like without affecting the other.
