Youre in the movie image incrustation

[Valcriss]

I recently see an online test of Youre in the movie a codemaster game

French test link i sure you will find an english one

I wanted to try to make something like a webcam video incrustation, to see what i can do with it.

I am just a the beguining, here is what ive got :

I would like to find a way to optimise the "character" detection, and may be find how to generate some kind of Bounding Box around him.

If someone have any clues.


Edit : this source use Philip Pierce's Webcam capture control (link)

This looks like a task for a GPU.

Have you considered working with a TVRenderSurface and shaders for this?
Like, textures for the reference/with-character/background images, and a rendersurface for the final composite. Then you pass this to a shader and use fancy alphablending to composite it together. You could do much more logic per-pixel too, since it'll be much faster.

I guess the bottleneck then becomes feeding the webcam image as a texture. There's probably an efficient way to do this, maybe with an unsafe block.

Hum that the thing i must learn "shaders" 

Well i think it will be a good way to learn 

If someone know a good "i am very new to shaders and want to make an hello world" book

[ZaPPZion]

Yea i know one I'd recommend it to anyone who's trying to learn shaders, since i learned it pretty fast with that book.

"Shaders for game programmers and artists" written by Sebastien St-Laurent

It covers a lot of basic shaders, but also a couple more advanced shaders.

I have just bought it on amazon, will receive it in 2 weeks, thank you!

i had some decent results using the aforge image filters.

this seems to be very interesting thank you 

[Zaknafein]

This looks excellent. And having all the bounding/movement/shape detection maths already done for you is a huge plus.

I'm a shader guy so shaders came to mind first, doesn't mean it's the best solution.

I will try to implement the motion detection algorithm at the end of this week.

While i was searching for this kind of stuff i found this project :

With this very impressive video :

I dont think i will use it on my "i want to dance in front of my webcam" test game, but i wanted to share this link.
