Abstract :
Most of the existing methods are focused on HDR image generation for static scenes. However, these methods are not effective for the scenes with moving objects. In this paper we present an algorithm that generates High Dynamic Range (HDR) images from three differently exposed Low Dynamic Range (LDR) images taken from different viewpoints. It allows generating HDR images for scenes with fast motion or from moving vehicle. Image alignment is based on optimized MTB algorithm. Error correction for occluded parts of the scene is solved by using error maps based on image correlation and bilateral smoothing weight. Fast exposure-blending technique is applied to aligned images in order to produce HDR image.
