The meaning of data (information) hiding is to embed the secret information into a cover host, such as an image. Usually, the naked eye of the people cannot perceive any change when the image is modified slightly. The evaluation of data hiding schemes should be measured by the distortion (or called Mean Square Error; MSE) and the embedding rate (the average number of bits embedded in a cover pixel). In this paper, we propose two improved data hiding schemes. One is to improve the EMD (Exploiting Modification Direction)-based data hiding algorithm to have higher stego-image quality. The other is to improve the Matrix encoding-based data hiding algorithm by using the idea of Hamming+1 to further improve the stego-image quality. Both proposed improved schemes are verified to be correct through the theoretical analysis and the experiment.

In the paper, we proposed a gender recognition scheme based on multi-model information fusion. The proposed gender recognition scheme is composed of four parts: face detection and rectification, eye detection, feature extraction, and gender classifier. To evaluate the proposed scheme, a large number of images containing different-size faces are captured by using low-cost webcam. Experimental results show that our proposed scheme can detect facial regions as well as eyes well. In addition, the accuracy of our gender recognition scheme is more than 95%. These results demonstrate that our proposed scheme can achieve not only face and eye detection but also gender recognition.
In this paper, a novel reversible watermarking method based on the adap- tive IWT-coefficient adjustment is proposed. A host image is first decomposed into the integer wavelet transform (IWT) domain. Subsequently, a s...

News articles have always been a prominent force in the formation of a company's financial image in the minds of the general public, especially the investors. Given the large amount of news being generated these days through various websites, it is possible to mine the general sentiment of a particular company being portrayed by media agencies over a period of time, which can be utilized to gauge the long term impact on the investment potential of the company. However, given such a vast amount of news data, we need to first separate corporate news from other kinds namely, sports, entertainment, science & technology, etc. We propose a system which takes news as, checks whether it is of corporate nature, and then identifies the polarity of the sentiment expressed in the news. The system is also capable of distinguishing the company/organization which is the subject of the news from other organizations which find mention, and this is used to pair the sentiment polarity with the identified company.
