Natural images have a strong correlation between adjacent pixels and its disturbed by LSB matching. Accordingly the effects of LSB matching steganography on neighborhood node degree were examined at first. Then features were extracted from neighborhood node degree histogram. A new calibration algorithm based on neighborhood node degree was proposed to get more effective features. Support Vector Machine (SVM) was used as classifier. Experimental results demonstrated that the proposed method was efficient to detect the LSB matching steganography and had superior results compared with other recently proposed algorithms on compressed images and low embedding rate uncompressed images.]]>Berg, G., I.
