Abstract
A HDR tone mapping system includes several modules. A semantic segmentation module is used to extract semantic information from the input image. An image decomposition module is used to decompose the input image to a high-bit base layer and a detail layer. A statistics module is used to generate statistics of pixels of the input image according to the semantic information. A curve computation module is used to generate a tone curve from the statistics. A compression module is used to compress the high-bit base layer to a low-bit base layer according to the tone curve, the statistics and the semantic information. A detail adjustment module is used to tune the detail layer according to the semantic information and the statistics to generate an adjusted detail layer. An image reconstruction module is used to combine the adjusted detail layer and the low-bit base layer to generate an output image.
