Real-time Implementation of An Exponent-based Tone Mapping Algorithm
Abstract
In this thesis, we present a real-time hardware implementation of an exponent-based tone mapping algorithm of Horé et al. Although there are several tone mapping algorithms available in the literature, most of them require manual tuning of their rendering parameters. However, in our implementation, the algorithm has an embedded automatic key parameter estimation block that controls the brightness of the tone-mapped images. We also present the implementation of a Gaussian-based halo reducing filter. The hardware implementation is described in Verilog and synthesized for a field-programmable gate array (FPGA) device. Experimental results performed on different wide dynamic range (WDR) images show that we are able to get images which are of good visual quality and have good brightness and contrast. The good performance of our hardware architecture is also confirmed quantitatively with the high peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) index.
