Abstract :
High Dynamic Range (HDR) imaging represents a wide range of intensity levels found in real scenes ranging from direct sunlight to shadows. However, raw HDR sequences require very huge memory space for storage. In this work, we present an approach of how an existing encoder can be used for encoding HDR video sequence with our proposed adaptive LogLuv transform. The proposed method shows considerable improvement when compared with non-adaptive LogLuv transform.
