Detection of Images Steganography Algorithm Based on Wavelet Packet Decomposition and Support Vector Machines
Qing Qin · Jisuanji gongcheng · 2005
A new algorithm of decomposition has been introduced, namely to decompose the lowpass subbands of image, so the dimensions of characters vector accordingly are decreased largely and the running efficiency is increased. In the pattern discrimination, the support vector machine algorithm is used, the experiments results show, the detection rate is increased evidently than Fisher linear discrimination.
