Image Resolution Up-Conversion via Maximum a Posteriori Interpolator Sequence Estimation and Viterbi Algorithm
Abstract
A new method of image resolution up-conversion based on maximum a posteriori sequence estimation is proposed. At each missing pixel of the high resolution (HR) image we consider an ensemble of candidate interpolation methods (interpolator). The interpolators are interpreted as states of a finite-state machine (FSM). Accordingly, the up-scaling problem is converted to the problem of estimating the optimal sequence of interpolators corresponding …
