Visualizing Pattern Constancy - Webcams

Time-Series Studies - San Marino Mountainside

...when lossy JPEG compression seriously limits pattern constancy

In order to build a comprehensive demonstration of canonical representation and
pattern constancy, we examine time series imagery of the same scenes under widely
varying imaging and sensor exposure conditions. Our intent is to demonstrate that any
specific scene can be encountered again and again with widely changing extraneous
variations and still produce a processed result which maintains a high degree of visual
representation consistency and pattern constancy.
