An increasing number of images in the Internet brings forward a higher requirement on the speed of steganalysis. For the problem of real-time detection of stego images, a rapid images steganalysis method based on identifiable features is proposed, where the identifiable features are specific character sequences left in stego images by steganography tools. The stego and cover images are distinguished...

An object detection algorithm which can remove moving cast shadows is presented. It is based on the homography mapping of foreground regions from multiple cameras. Not only the homography for the ground plane but also those for multiple parallel planes are employed. Unlike the existing geometric approaches, this algorithm removes cast shadows while keeping the feet of moving objects.
This paper presents an object detection algorithm using multiple cameras, which is robust in the presence of cast shadows. The information fusion is based on homography mapping of the foreground regions to a top view image. The homography is based on multiple planar planes parallel to the ground plane. Two novel approaches to estimating such homography have been proposed. The results on an open video...
