ABSTRACT

Adaptive Local Image Registration is a Local Image Registration based on an Adaptive Filtering frame work. A filter of appropriate size convolves with reference image and gives the pixel values corresponding to the distorted image and the filter is updated in each stage of the convolution. When the filter converges to the system model, it provides the registered image. The filter size plays an important role in this method. The analysis on the filter size is done using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity (SSIM) index. Analysis shows that the convergence action of filter would negatively affect by a small increase in filter size. If the displacements between the images are large, it requires a large filter.
