Figure 1 : An example of an HDR digital image of the RIT color cube rendered using the iCAM image appearance model to simulate human perception of the scene and (inset) rendered linearly. Abstract Recently, the field of color appearance modeling has been extended further into the spatial and temporal domains through efforts known as image appearance modeling. Image appearance models have applications in rendering and visualization of image data, cross-media image and video reproduction, and
