Abstract: In this paper we propose a better energy and bias field estimation method called optimized multiplicative intrinsic component optimization. This method takes the responsibilities of decomposing the image into two multiplicative components, such as true image and bias field components for hyper spectral images in dark night regions. These components simultaneously derived by energy minimization and the process mainly aimed at achieve the optimum intrinsic components of Synthetic Aperture Radar (SAR) image. In this SAR image processing we are introducing a novel technique for minimizing the energy function by bias field estimation. This method performs two operations to optimize the intrinsic multiplicative components. These are bias field estimation and energy minimization. Our proposed method becomes robust due to convex of each variable in energy minimization algorithm. The performance of the proposed scheme is evaluated by comparing with conventional techniques.
