Abstract

Abstract- this paper proposes an algorithm for the removal of ghost artefacts in order to yield a “high dynamic range” (HDR) image which is free from ghost artefacts which result because of camera’s movement. The condition of working of current HDR images is that camera does not move during the acquisition of multiple “low dynamic range” (LDR) images. Such unrealistic restriction is overcome by specifying the target first and in an acquired set of LDR images, a source image is also specified and then estimation of rotational components and translational components is done in affine matrix for transforming the source image to fit into target image. The HDR image will be reconstructed by the proposed algorithm without having ghost artefacts as there is no camera movement in transformed images. The results show the successful removal of ghost artefacts. This is the reason which extends the application of proposed algorithm from HDR imaging to several devices of mobile imaging such as mobile phone camera and camcorder.
