Title:

    iCAM for high-dynamic-range image rendering

Presenter(s)/Author(s):



Abstract:


    Traditional color appearance models, such as CIECAM02, are intended for prediction of stimulus’ color appearance in somewhat simplified viewing conditions. It is normally assumed that a uniformed color patched is viewed on a uniformed background with different color. However, images are more complex than that. Image appearance model (iCAM) [Fairchild and Johnson 2004] has been proposed to extend the traditional approaches to predict more complex stimulus in a wider array of viewing environments that are varied spatially and temporally, and has shown great potential in a variety of applications. In this poster, a new iCAM framework was presented for the application of rendering high-dynamic-range (HDR) images or scenes into limited dynamic-range displays. Furthermore, this model is designed to predict how real-scenes perceptually appear by incorporating the prediction of color appearance effects such as the Hunt effect, the Steven effect and the surround effect.
