Single image-based HDR imaging with CRF estimation

Abstract

Single image-based HDR imaging can inherently remove ghost artifacts which appear in multiple image-based HDR imaging. Most existing single-exposure HDR imaging methods apply complicated handing to overexposed areas in image, which perplexes the algorithm and introduces the probability of generating artifacts; moreover, they do not take into account the imaging properties of the camera. In this paper, we proposed a single image-based HDR imaging based on camera response function (CRF) reconstruction. The HDR image is obtained by performing the reverse CRF on the original LDR image. The imitation of imaging procedure inherently makes the final HDR image be high quality. The experimental results show that the proposed approach performs well and produces favorable images.
