Virtual HDR/LDR image synthesizer in multi-core platform

In this paper, we analyze the performance of implementing inverse tone mapping operation in various multi-core environments. We parallelize the procedure of producing five HDR images and weighting value, the ratio of the two functions decreases and the total simulation time decreases around 50% under six-core environment. The reduction is because these functions are parallel implemented with multi-thread on multi-core platform. The hardware performance analysis shows that our proposed method is easy to be realized in a multi-core system to speed up the performance. In our future work, we will study the effects and performance of applying our method to video.
