In this paper we recommend a novel method for high dynamic range image acquisition (HDRI) which is performed by combining multiple images taken with different exposures and estimating the irradiance values of each pixel, under various types of occlusion (object to object and object to scene occlusion) and scale change of object (small or large object) in real-time video. This is a common process for HDRI acquisition. In our approach firstly we apply some methods in original images like grey conversion, binary conversion, filter conversion, image resize, image sharpening to remove noise and to avoid minute changes in the image. By using the MAP (Maximum a Posteriori) estimation we can easily estimates displacement, occlusion and saturated regions simultaneously. In this paper we present the efficient and accurate multiple exposure fusion technique for HDRI acquisition to address the problems....
