A pattern-based inter-/extra-polation approach for image scaling

Abstract

A novel approach to simultaneous scaling and enhancing of a digital image is proposed, where efficient code matching is utilized to classify various edge/corner patterns. Adaptive schemes of inter-/extra-polations are adopted to maintain a balance of smoothness and sharpness of the scaled image, with unlimited scaling factors. Unlike many complex methods for image scaling and enhancement, our approach is very simple, making hardware implementation feasible.
