An optimization framework for inverse tone mapping using a single low dynamic range image

作者：

Highlights：

• A novel optimization framework for inverse tone mapping (TM).

• A high-quality HDR image is iteratively reconstructed.

• Any differentiable and invertible TM operator can be applied to our framework.

• The high luminance region is further enhanced by the post-processing.
