Today I read a paper titled “Spatiotemporal sensistivity and visual attention for efficient rendering of dynamic environments”
The abstract is:
We present a method to accelerate global illumination computation in dynamic environments by taking advantage of limitations of the human visual system.
A model of visual attention is used to locate regions of interest in a scene and to modulate spatiotemporal sensitivity.
The method is applied in the form of a spatiotemporal error tolerance map.
Perceptual acceleration combined with good sampling protocols provide a global illumination solution feasible for use in animation.
Results indicate an order of magnitude improvement in computational speed.
The method is adaptable and can also be used in image-based rendering, geometry level of detail selection, realistic image synthesis, video telephony and video compression.
