Abstract:
Techniques are disclosed for coding high dynamic range (HDR) data. According to such techniques, HDR data may be converted to a domain of uniform luminance data. The uniform domain data may be coded by motion compensated predictive coding. The HDR data also may be coded by motion compensated predictive coding, using a coding parameter that is derived from a counterpart coding parameter of the coding of the uniform domain data. In another technique, HDR data may be coded using coding parameters that are derived from HDR domain processing but distortion measurements may be performed in a uniform domain.
