| dc.description.abstract | Tone mapping algorithms are used to adapt captured wide dynamic range (WDR) scenes to the limited dynamic range of available display devices. In this thesis, a real-time hardware implementation of an exponent-based tone mapping algorithm is presented. An automatic parameter selector was designed for this algorithm in order to achieve good tone-mapped images without manual reconfiguration of the tone mapping algorithm. Both algorithms were implemented in Verilog and synthesized for an FPGA device. The hardware architecture employed a combination of parallelism and system pipelining so as to achieve a high performance in power consumption, hardware resources usage and processing speed. In addition, modifications to the tone mapping algorithm were implemented so as to increase the image and video quality of the tone-mapped image frames. Objective image quality assessment shows that the improved tone mapping algorithm attains higher image quality scores than the original tone mapping operator. | en_US |
