    A backward compatible HDR encoding scheme



    Two-layer encoding schemes for HDR images (and video) can not only reduce the storage requirements, but more importantly they can also ensure backward compatibility during transition from LDR to HDR age. The first layer is a tone-mapped LDR image, which can be shown on existing displays. The second layer is another LDR image and contains the residual information lost in tone-mapping, which can be used by HDR applications.
