Contrast Preserving Tone Reproduction for High Dynamic Range Images
(Institute of Electrical and Electronics Engineers Inc., 2016) Jaiswal, S.; Tripathi, A.K.
An exact replica of a high dynamic range image which embeds withinit a wide range of luminance values on a standard display device(e.g. LCD monitor) is impossible to achieve without significant lossof information as the display devices are designed to handle verylow range of intensity values compared to the high dynamic rangescene. We propose an algorithm whose output is visually pleasingand preserves maximum information from the input image. In additionto that, proposed method is fast and easy to implement. Proposedalgorithm uses the local and global histogram information of theimage and produces the best tone mapped image. Results verify theefficiency of the algorithm. Proposed algorithm requires noparameter adjustment which makes it useful for any image dataset. Â© 2016 IEEE.
