A Subdivision-Based Image Interpolation Method on Android Platform

How to satisfy the need of Android users to get high-resolution images quickly becomes a hot issue of research in recent years. We propose a new image interpolation algorithm based on the Loop subdivision. Similar to the refinement of meshes, Subdivision methods can also generate new pixels on images. In order to preserve the sharp edges, We propose a rational subdivision scheme by adjusting the weight coefficients of pixel vertices. This algorithm runs quickly and accurately on the Android platform by using Android NDK.
