Patent number: 10931961Abstract: A method for encoding high dynamic range (HDR) images involves providing a lower dynamic range (LDR) image, generating a prediction function for estimating the values for pixels in the HDR image based on the values of corresponding pixels in the LDR image, and obtaining a residual frame based on differences between the pixel values of the HDR image and estimated pixel values. The LDR image, prediction function and residual frame can all be encoded in data from which either the LDR image of HDR image can be recreated.Type: GrantFiled: October 15, 2018Date of Patent: February 23, 2021Assignee: Max-Planck-Gesellschaft Zur Forderung Der Wissenschaften E.V.Inventors: Alexander Efremov, Rafal Mantiuk, Grzegorz Krawczyk, Karol Myszkowski, Hans-Peter Seidel
