A digital image stabilization algorithm based on polar transform and circular block matching is utilized in this paper to stabilize the videos, taken from rolling airborne platform, which have rapid rotation and arbitrary translation changes between adjacent frames. And circular block matching is used to estimate the global motion parameters, the hierarchical search strategy to reduce the amount of...
We present a performance evaluation framework for visual feature extraction and matching in the visual simultaneous localization and mapping (SLAM) context. Although feature extraction is a crucial component, no qualitative study comparing different techniques from the visual SLAM perspective exists. We extend previous image pair evaluation methods to handle non-planar scenes and the multiple image...
