Dynamic Range Adjustment of HDR Images Using Adaptive Method

The ratio of a variable measurement's maximum and minimum values is known as its dynamic range. This range, as it relates to photography and cinematography, is the proportion between an image's whitest (brightest) and darkest (darkest) values. The main goal here is to enhance the detailed visibility of scenes. In this research, we present a three-adaptive step approach for image dynamic range modification that is both efficient and effective in terms of visibility and ease in use. First, two Gamma functions are adaptively selected on the basis of the histogram of the brightness map independently. Second, to balance the amplification of details in different places, an adaptive fusion technique is presented to integrate the two modified luminance maps. Finally, we propose a method to restore the color to the fused image.
