Image steganography detection algorithm based on locality preserving projections
Xiaoyuan Yang · Computer Engineering and Applications Journal · 2009
A new image steganography detection algorithm based on locality preserving projections has been introduced.In order to reduce the dimensionalities of the image feature set,keep its low dimensional structure and make the classifier more effective,after forming the image features set via wavelet transform,the algorithm projects the set to a low dimensional one and gets the inner manifold by using the LPP algorithm.Support vector machine classifier is used to classify the image set.It is testified that in contrast with algorithm without dimensionality reduction,this algorithm can improve the performance signature signally.
