Abstract
This paper presents a two layer CODEC architecture for high dynamic range image compression. The first layer contains the tone mapped image obtained using a conventional low dynamic range encoding approach, such as JPEG. The second layer contains the image difference, in perceptually uniform colour space, between the result of inverse tone mapped low dynamic range content and the original image. We present techniques for efficient implementation and encoding of nonuniform tone mapping operators. Different colourspaces and compression algorithms are compared.
