Two-stage image restoration using improved atmospheric scattering model

Image Restoration Using A PDE-Based Approach

 Image restoration is an essential preprocessing step for many image analysis applications. In any image restoration techniques, keeping structure of the image unchanged is very important. Such structure in an image often corresponds to the region discontinuities and edges. The techniques based on partial differential equations, such as the heat equations, are receiving considerable attention i...

Image Restoration with Two-Dimensional Adaptive Filter Algorithms

Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...

Image Restoration Using Two-Dimensional Variations

A two-stage model for ranking DMUs using DEA/‎AHP‎

‎In this paper, we present a two-stage model for ranking of decision making units (DMUs) using interval analytic hierarchy process (AHP). Since the efficiency score of unity is assigned to the efficient units, we evaluate the efficiency of each DMU by basic DEA models and calculate the weights of the criteria using proposed model. In the first stage, the proposed model evaluates decision making...

An Improved Decomposition Based Fusion Model for Medical Image Restoration

Image fusion is about to combine the features of two or more partial occluded or damaged images to generate a new effective image. Some image sequence is generated; sometimes some images are not taken well because of lighting problem, instrument problem etc. In such case, by combining the two or more image visible features, a faire image can be constructed. In this present work, ROI analysis ba...
