Re: [WM]: Best LSB-Steganalysis algorithm
hi all,
sorry for delay, but I'm a little busy right now; so I'll send u more info on our steganography method soon; and I'll also send some
sample photo with embedded data.
about the capacity, I tested it on 108 photos from kodak image database, an= d the average of embedded message in which RS could not
detect (ie. detected it lower than 3%) was 22%. and for some samples the capacity was very high.
for example in best experience, I could embed 70% data that RS could not detect it.
yours
