function for vectorizing an image-batch pixelwise

Hello

I have an batch/bunch of images which are a result of a filterjet. For further inspection of some statistics of these images i need a accelerated function, that imports the pixelvalues of the images into vectors like this:

vector0 = [image0(0), image1(0), image2(0), ... imageN(0)];
vector1 = [image0(1), image1(1), image2(1), ... imageN(1)];
...
vectorM = [image0(M), image1(M), image2(M), ... imageN(M)];

where imageX(Y) means the Y-th pixel of image X (the image is regarded as 1-dim-vector).

Is there a (bunch of) predefined functions that can do that ?

Thanks for help in advance

best regards

M.W.

edit: alternatively an image can be used, where the vectors are arranged horizontally.

Hi M.W.

It looks that these data are transposed ( you can check the transpose functions).

The original data are organized as:

[image0(0), image0(1), image0(2), ... image0(m);]
[image1(0), image1(1), image1(2), ... image1(m);]
[image2(0), image2(1), image2(2), ... image2(m);]

The transposed data is like:

[image0(0), image1(0), image2(0), ... imageN(0)];
[image0(1), image1(1), image2(1), ... imageN(1)];
...

[image0(M), image1(M), image2(M), ... imageN(M)];


Maybe you cancheck if such functions can provide some help.

Thanks,
Chao
