Thread Subject: how to convert a 2D image into 3D

Hello all matlab users

I am working on image processing tool of matlab

I need an algorithm written in matlab to convert the 2D
image into 3D image.

Is there any body to help me.

hi

have you converted the 2d image to 3d.

i too need the algorithm in matlab

There is some confusion about 2D and 3D image. Indexed image and gray scale image may be taken as 2D image and rgb image may be taken as 3D image, regarding the data matrix representing those images. This interpretation may be different from the viewing point of view. To convert a 2D view to 3D view, we need to mapped using the orthogonal projection at proper viewing angle. Here viewing angle plays a very important role.

Hi, did you try with surf or mesh?
For example,
x = imread('foo.bmp');% its 2D image
xx = double(x);
y = imagesc(xx)% gives 2D image
z = mesh(xx)% gives the pixel values as 3rd dimension.
Enjoy it
