We propose a three-level video-event detection methodology and apply it to animal-hunt detection in wildlife documentaries. The first level extracts color, texture, and motion features, and detects shot boundaries and moving object blobs. The mid-lev

We consider the problem of estimating the 3D motion of an articulated object, such as a robot arm or a human body, from a monocular sequence of 2D perspective views. We advocatte an approach of decomposition. The object under analysis is decomposed i

This paper presents a new edge detection scheme that detects two-dimensional (2-D) edges by a curve-segment-based detection functional guided by the zero-crossing contours of the Laplacian-of-Gaussian (LOG) to approach the true edge locations. The de

An algorithm is presented for replacing video background without a physical blue screen. The method requires pre-recording a background image of the scene without the presence of any foreground objects. Based on the color difference between the pixel
