F5-a steganographic algorithm

WebStego images are generated with variations in payload using steganographic algorithms. From the training data, complex features are extracted using feature extraction methods. SVM classifiers are trained with the feature vectors. This research work was exclusively based on the design of steganalysis for LSB-based steganographic schemes. Websteganography, such as OutGuess [4], F5 [5], and Model-based (MB) [6]. The feature extraction algorithm of the steganalyzer [3], however, is complicated and takes time. The above mentioned steganalysis schemes [1, 2] are both based on the statistics of the histogram of wavelet subbands. (Note that the scheme [2] is partially based on
