This paper presents a real-time face detection algorithm for locating faces in images and videos. This algorithm finds not only the face regions, but also the precise locations of the facial components such as eyes and lips. The algorithm starts from the extraction of skin pixels based upon rules derived from a simple quadratic polynomial model.(More)

A computer vision-based system using images from an airborne aircraft can increase flight safety by aiding the pilot to detect obstacles in the flight path so as to avoid mid-air collisions. Such a system fits naturally with the development of an external vision system proposed by NASA for use in high-speed civil transport aircraft with limited cockpit(More)
Computer graphics animation often lacks interaction between rigid object and granular material. In this paper, we propose a method for the deformation of the ground surface that consists of granular material when it penetrated by a rigid body object in motion. Meanwhile, the motion of the rigid object is also affected due to the collision with the ground(More)
The National Aeronautics and Space Administration (NASA), along with members of the aircraft industry, recently developed technologies for a new supersonic aircraft. One of the technological areas considered for this aircraft is the use of video cameras and image processing equipment to aid the pilot in detecting other aircraft in the sky. The detection(More)
The High Speed Civil Transport (HSCT) supersonic commercial aircraft under development by National Aeronautics and Space Administration (NASA) and its partners is expected to include an external Visibility System (XVS) to aid the pilot's limited view through their cockpit windows. XVS obtains video images using high resolution digital cameras mounted on the(More)
