This paper presents a novel FPGA architecture of high dynamic range (HDR) video
processing pipeline, based on the capturing of a sequence of differently exposed
images. An acquisition process enabling multi-exposure HDR as well as fast
implementation of local tone mapping operator involving bilateral filtering is
proposed. The HDR acquisition process is enhanced by the application of novel
deghosting method, which is dedicated for hardware implementation and proposed in
this paper. The hardware processing pipeline is designed with regards to
efficiency and performance and the calculations are performed in fixed point
arithmetic. The pipeline is suitable for programmable hardware (FPGA-Field
Programmable Gate Arrays) implementation and it achieves real-time performance on
full HD HDR video which overcomes state-of-the-art solutions that use local tone
mapping and deghosting algorithm.
