A Novel Approach for Reduction of Dynamic Range Based on Hybrid Tone Mapping Operator

In our proposed model a hybrid method of tone mapping is presented. In this technique, an image of High Dynamic Range (HDR) is employed as input and split up into two layers i.e. base and detail layer. The details of HDR image will be preserved because only the base layer's contrast is brought down. A bilateral filter is used to obtain the base layer. Along the base layer the logarithmic compression is used and a bias power function is employed so that the logarithmic base can be varied adaptively and the contrast remains preserved. This tone mapping technique produces a high quality tone mapped image as specified in given experimental results.
