Aimed to improve the detection efficiency of information-hiding blind detection system, the present study proposes an SADRID-I image steganalysis algorithm that is based on improved differential matrix, according to the high dimensions and correlation of image features. Using attribute significance and differential matrix that stems from rough sets theory, the algorithm can implement D attributes...
Recently, many vision-based robotic applications such as visual SLAM (Simultaneous Localization And Mapping) and autonomous navigation have achieved good performance using visual features. In these applications, robust feature tracking plays an important role, e.g., in scene recognition for autonomous navigation and in data association for visual SLAM. In this paper, we propose a hierarchical outlier...
