convert cvs file to image format

Dears

i need help ....

i had convert image to cvs for training image data using machine learning. because i faced problem to train image directly.

I had used the following command and it was work but not with converting csv to image :

%m = imresize(e ,[256 256]); %AF_O = cast(m,'double'); %imwrite(AF_O,['Result','.png'],'png');
