    Perceptually-informed accelerated rendering of high quality walkthrough sequences
    (The Eurographics Association, 1999) Myszkowski, Karol; Rokita, Przemyslaw; Tawara, Takehiro; Dani Lischinski and Greg Ward Larson
    In this paper, we consider accelerated rendering of walkthrough animation sequences using combination of ray tracing and Image-Based Rendering (IBR) techniques. Our goal is to derive as many pixels as possible using inexpensive IBR techniques without affecting the animation quality. A perception-based spatio-temporal Animation Quality Metric (AQM) is used to automatically guide such a hybrid rendering. The Pixel Flow (PF) obtained as a by-product of the IBR computation is an integral part of the AQM. The final animation quality is enhanced by an efficient spatio-temporal antialiasing, which utilize the PF to perform a motion-compensated filtering.
