Abstract
Motion artefacts (ghosting) can be produced in HDR images due to moving objects in the input LDR dataset. This work aligns all LDR images with a reference image, and thus removes ghost artefacts in the HDR image. This is done without explicit detection of moving regions in LDR images. Intensity scaling factor between the reference image and target image is estimated by taking into account only non-moving and non-saturated pixels, and it is used as an index to determine moving pixels in target image. Finally, the values of the moving pixels in target image are corrected with their expected values. The method is more accurate than the existing methods with competitive computation speed.
