but without more info not sure.

I'm not too sure either, but my guess it's what he is looking for.

@Olof Hedman , jwezorek , eppo ,

thanks ,

so you say visualisation (rendering , ray...etc) are different from Computer Vision field , and they don't relate?

Q1 : Okay
Olof as you say , I have to take signal processing course and random theory as prerequisites for Computer vision right?

jwezorek ,

I wanna to take data from Camera and capture objects with accosiated with it's cloth ( Material ) and import them into 3D max and export it as Model ready for game engine without needs to make materials in 3d application smile.png (the problem I don't know anything about signal processing !!!!! because Olof says ,"understand and interpret signals " :(


Q2 : So thats why I am asking , is there a field in computer vision close to Visualization (Rendering , tracing ...etc) or not ?

I wanna to take data from Camera and capture objects with accosiated with it's cloth ( Material ) and import them into 3D max and export it as Model ready for game engine without needs to make materials in 3d application

I don't know ... but I'm afraid extracting 3D models and material information from a 2D image in a completely unsupervised manner is beyond the state of the art of computer vision today. Unless I'm misunderstanding...

Actually, you can do it, if you have several images of the object from different angles.

But it's a very advanced subject, and you will not get models you can use directly in a game.

One low cost solution for a simple "3D scanner" is to use one (or two for better accuracy) kinects.

The API is open, and you get 2 images, one normal camera image, and one depth image, with the distance from the kinect to each point in the camera image.

I'm pretty sure you can find some software to do it out there, at least there are for motion capture.

But any model extracted from it would also be very noisy and need extensive cleanup to be usable in a game.

But it seems it is computer vision you want, after all.

I don't have any tips for any books unfortunately...

Y
ou says that there are many fields in computer vision , so what is the one that is good for my project ?
jwezorek

you are right :) that's what I want from "2D -> 3D"

I used google and found that Computer vision in general the mathmematics requirements are :
geometry ( any recommended books ?)
Optimiazation ( what you prefer for Optimization : " linear programming " , "complex analysis ")
statistics ( I think introduction to probability course is good !)
and about physics prerequisities books for computer vision :
I think that digital signal processing is enough !
