This file shows four methods of tone mapping image sequences
 (video). Each method contains approximately 8 seconds of video. In
 each method there is some apparent banding on the ceiling, but this
 is an artifact of the scene and not the methods. We have compressed
 the original image sequence (30 frames per second) into an avi video
 which contains only 15 frames per second due to bandwidth
 constraints.

Method 1: In this method, the high dynamic range images are clamped. A
 value for white is chosen and the resulting colors are clamped to
 this value.  There are no temporal artifacts because each frame is
 clamped to the same white value.

Method 2: The HDR images are scaled in this sequence to show all
 colors in an LDR range. This gives the overall sequence a 'dull' look
 and appearance. Also, since there is no temporal coherency, large
 flicker occurs. Between 13 seconds and 14 seconds this is very
 obvious.

Method 3: The image sequence was then rendered using the temporal
 method presented by Kang et al. in Siggraph 2003. This method
 maintains richness of color early in the image sequence. However, as
 the change in luminance occurs (22 seconds), the image takes on a
 dull appearance similar to the scaled method.

Method 4: Method four demonstrates our method. The image sequence
 maintains temporal coherency and richness of color throughout the
 sequence. It is interesting to compare the blue color in painting on
 the right wall in Method 3 (24 seconds) to our method (30
 seconds). In these same two frames, richness in the highlights on the
 floors and walls are also features of our method.
