| Abstract | Various tone mapping operators are available for mapping the high dynamic range images to displayable low dynamic range image. In this paper, the performance of various tone mapping operators are evaluated and compared. Multiple exposure photos are combined together to form a high dynamic range image and tone mapping operators are applied to form a LDR image and the tone mapped images are compared with the original image. Tone mapping is also applied directly on a high dynamic range image and the result is compared with the original image. Color correction formula [13] is applied on the tone mapped images to enhance the image quality and the effect of color correction is also evaluated. Piecewise Tone mapping operator [3] is improved by applying Hierarchical tone mapping operation [4] to enhance the quality of the tone mapped image | |
