Abstract

The advantages of the maximum a posteriori framework for the super-resolution problem like reconstructing high-resolution images from shifted, rotated, low-resolution degraded observations with both synthetic and real data is demonstrated.

Abstract

Two algorithms for the problems of obtaining a single high-resolution image from multiple noisy, blurred, and undersampled images are proposed using a stochastic framework. Experiments show that the proposed joint estimation approaches offer significantly more accurate and robust estimation of the unknown registration parameters as compared to the conventional approaches that employ registration as an independent estimation procedure during processing.
