Real-time Video Mosaicing with Adaptive Parameterized Warping
Le Lü, Xiangtian Dai, Gregory D. Hager · 2003
This paper briefly describes a system for real-time video mosaic construction using intensity-based registration. One novel aspects of this algorithm is a dynamic selection of warping models, including similarly transforms, affine models, projective models, and quadratic models based on the complexity of the incoming imagery. A second result is a new method for subsampling the images based on the sensitivity of image pixels in template matching. By exploiting the latter, it is possible to greatly accelerate the calculation. Some real image sequence mosaicing results for different parametric models are shown in this paper. These are all processed in real-time.
