Abstract:

In recent years, the high dynamic range (HDR) image has received extensive concern in image research area and applications, and it has been a research focus in image processing area. The capture technology and encoding format of HDR images are introduced firstly, then the existing inverse/reverse tone mapping operators (iTMOs) to obtain HDR images from low dynamic range images are classified. The key characters of these operators are compared and discussed. These lay the foundations for the application and research of the iTMOs.
