INVESTIGATION OF HIGH DYNAMIC RANGE IMAGE REGISTRATION ALGORITHM

Dynamic imaging technology has a wide range of applications. High dynamic image (HDR) can obtain better realism and has irreplaceable advantages over traditional image. Compared with the hardware implementation, the software algorithm using multiple photos with different exposures has the advantages of simpler and lower cost. However, multiple images are prone to different degrees of displacement, which requires image registration technology for image registration. The main contents of this paper are image registration related technology, image synthesis, camera response function fitting, color synthesis and so on. The core problem is to study image registration technology, including mean binarization (MTB). This is an important link in the process of HDR image synthesis and has important practical significance.
