VideoBrushTM: experiences with consumer video mosaicing

We present technical advances that were made in creating consumer level video mosaicing applications with inputs from hand held inexpensive cameras, and with near-real time response. In developing the VideoBrush^TM technologies, the goal was to give easily usable but robust video mosaicing capabilities in the hands of lay users. We highlight a number of problems that needed to be solved to enable this: 2D & 1D modes of scene scanning and alignment, progressive complexity of alignment models to provide real-time response to the user and multi-resolution blending for high quality mosaic output. The solution to these key technical challenges has led us to video mosaic technologies that can “scan” scenes as diverse as natural panoramic scenes to white boards and documents
