Do you need 12 bits for image quality or just to test some algorithm? If
the latter is the case, given that the LSBs usually carry noise, why
not fill 4 additional bits in a 8bit picture with random data?

hello rajesh,
i am not able to understand what do you mean by monochrome images. You a
12/16 bit per sample Y(chroma) buffer? or what image format you need the
image in?
a simple 32 bit bitmap RGB image can be converted to a 8 bit/Y sample
greyscale image very easily. you can find the RGB-YUV conversion on the
net.

aps
could anyone send me some sample images of 12or 16 bit monochrome
thanks & regards
Rajesh.D
any format , 12 bit greyscale (RGB also ok) but the bit depth of Y
component
should be 12 bit and not 8 bit.
Ultimately i need one to test my algorithm for compression efficiency.
Surprising to see that google hasnt yielded a single image.
