problem with imwrite - rukmanimohan04 - Mar 23 13:08:00 2005




hi,
I am presently workin on datamarking of images using DCT. I have
created the datamark first by splitting the image into 8*8 blocks and
then applying DCT to each individual blocks. Then i got the marked
image using IDCT. i tried saving this image using imwrite and in bmp
format(the format of image i had used). the problem is when i use
this image which is saved using imwrite i m unale to extract the
information in the particular coefficients...Can anyone give me some
ideas regarding this aspect.
regds,
rukmani.
