implement hide using DCT

hi, i prepare a project about hide text into image using DCT, these is the algorithm

Input: Message, cover image

Output: steganographic image containing message

While data left to embed do 
 Get next DCT coefficient from cover image 
 If DCT not equal to 0 and DCT not equal to 1 then 
 Get next LSB from message 
 Replace DCT LSB with message bit 
 End if 
 Insert DCT into steganographic image 
End while

thanks

That only talks about the DCT itself, not about the information hiding. Most of the people who struggle with the task have difficulty in converting information into binary or back from binary, or get messed up by the fact that the output is likely to be floating point instead of uint8.
