AI Article Synopsis
- We developed a technique to capture and analyze light in a 7-dimensional structure, focusing on how light affects perception.
- Our method measures different light components, including diffuse and directed light, and tracks their changes over time, color, and direction.
- We tested this approach in real-world conditions, observing how lighting varies in different environments, like sunny versus cloudy days, and highlighted its benefits for understanding complex lighting effects on scenes and objects.
Article Abstract
We present a method to capture the 7-dimensional light field structure, and translate it into perceptually-relevant information. Our spectral cubic illumination method quantifies objective correlates of perceptually relevant diffuse and directed light components, including their variations over time, space, in color and direction, and the environment's response to sky and sunlight. We applied it "in the wild", capturing how light on a sunny day differs between light and shadow, and how light varies over sunny and cloudy days. We discuss the added value of our method for capturing nuanced lighting effects on scene and object appearance, such as chromatic gradients.
