Robust Parameter Estimation for Tone Mapping Operator
Tone Mapping Operators are used to compress a large range of pixel luminances into a smaller range that is suitable for display on devices with limited dynamic range. This work presents effective and easy to use Tone Mapping Operator based on last ideas in this direction. The estimation process uses sampling method. Essential attention was devoted to providing robustness of algorithm parameter ...
متن کاملModeling a Generic Tone-mapping Operator
Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the behavior of tone-mapping operators, we model their mechanisms by fitting a generic operator to an HDR image and its tone-mapped LDR rendering. We demonstrate that the majority of b...
متن کاملA Model of Retinal Local Adaptation for the Tone Mapping of Color Filter Array Images
We present a tone mapping algorithm that is derived from a model of retinal processing. Our approach has two major improvements over existing methods. First, tone mapping is applied directly on the mosaic image captured by the sensor, analogue to the human visual system that applies a non-linearity on the chromatic responses captured by the cone mosaic. This reduces the number of necessary oper...
