A New Tone Mapping Operator Based on Two-layer Model

Tone mapping is a process of compressing high dynamic range image data into low dynamic range data according to specific rules, so that the image can be displayed on ordinary display devices. The specific rules are called tone mapping operators. Nowadays, the mainstream tone mapping operator can be divided into two kinds, the global operators and the local operators. This paper processes a new tone mapping operator based on two-layer model. Our operator combines the characteristics of global operators and local operators, and it can effectively compress the high dynamic range images with an excellent performance.
