“…In this experiment, we have investigated the robustness of the proposed method against steganalysis methods such as Wavelet-based and Block-based steganalysis methods introduced in [24] [25]. Wavelet-based steganalysis [24] employs statistical features such as mean, variance, skewness, and SVM classifier to detect stego from clean image.…”

“…Wavelet-based steganalysis [24] employs statistical features such as mean, variance, skewness, and SVM classifier to detect stego from clean image. Other steganalysis method, Block-based steganalysis [25], divide image into sub-blocks , and then corresponds one classifier to each sub-block, and finally it uses a voting process to decide about stego or clean cover of whole image.…”

This paper presents a new steganography algorithm based on Morphology associative memory. Often, steganalysis methods are created to detect steganography algorithms using Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). In this paper, cover images are mapped to morphological representation by using morphology transform containing morphological coefficients, and each bit of secret message is inserted in the least significant bit of morphological coefficients. To evaluate stego quality, we measure the quality of the cover image after embedding by comparing with other image transformed steganography algorithms such as discrete cosine and Wavelet transforms. The quality of stego has considerably improved in comparison with the state-of-art methods. In the other experimentation, we test the robustness of our proposed method by using Wavelet and Block-based steganalysis methods. The results show a high level of robustness of our algorithm respect to other steganography algorithms.

“…And the features drawn from frames with high motion intensity are usually more effective than that from other frames. In image steganalysis, many frameworks [21][22][23][24] considering image content have been proposed, which guide the proposal of our approach. If we can extract features from subsequences of different motion intensity, the classifiers with features of different effectiveness can be trained independently.…”

This paper presents a steganalytic approach against video steganography which modifies motion vector (MV) in content adaptive manner. Current video steganalytic schemes extract features from fixed-length frames of the whole video and do not take advantage of the content diversity. Consequently, the effectiveness of the steganalytic feature is influenced by video content and the problem of cover source mismatch also affects the steganalytic performance. The goal of this paper is to propose a steganalytic method which can suppress the differences of statistical characteristics caused by video content. The given video is segmented to subsequences according to block's motion in every frame. The steganalytic features extracted from each category of subsequences with close motion intensity are used to build one classifier. The final steganalytic result can be obtained by fusing the results of weighted classifiers. The experimental results have demonstrated that our method can effectively improve the performance of video steganalysis, especially for videos of low bitrate and low embedding ratio.

“…Juned Ahmed Mazumder et.al [16], presented a DWT using high security steganographic technique & optimized message prpogeting method. Here they used Haar wavelet which decomposes both cover image into high and low frequency information.Where high frequency contains information about the edges, corners etc.…”

'Steganography is a art, which enforcing for obscur one part of data or information within another'. this paper shown an image steganography scheme which based on neural network fusion in wavelet transform domain. The cover and stego image is dividing in its frequency coefficients components by wavelet transform domain, and neural network used as classifier. This paper performed on the 256*256 size of image. All experimental result for this method will be performed in MATLAB language.
