In this paper, we propose the novel remote sensing image classification algorithm based on the PCA and hidden Markov random field theory. Remote sensing image classification method based on the pattern recognition theory at home and abroad, many experts have done a lot of research work, machine learning has been in study of remote sensing image classification and information extraction has been widely...
This paper proposes a method for building a real time lip reading system for Chinese characters. The Viola-Jones approach is adopted to detect the human face and lip area. By using this method, fast and exact extraction is accomplished. In the feature extraction module, an appearance based four-stage cascade method is proposed which includes the DCT-based and DWT-based image transformation, scanning...
