getting a picture in C - suganya boopathy - Aug 2 4:51:00 2003



Hai,

i am engaged in an image encoding project. could anyone of you help me on the
following?

1. how to acquire an image file in C language and a motion picture in C and
matlab?

2. for the acquired image, i have to perform 3D - DCT on that image. like dct2
for 2D DCT, we don't have inbuilt DCT program for 3 dimension. i need an
algorithm for writing 3D-DCT.

cheers.

To read the image in MATLAb you can use "imread" function.
eg. imread('lena.bmp')
