Mosaics from video with 'burned-in' metadata

【摘要】 In this paper, we discuss some of the challenges of computing mosaics from practical aerial surveillance video, and how these challenges can be overcome. One particular challenge is "burned-in" metadata, which occurs when metadata from the sensor and aircraft are burned into the actual pixel data. Another obstacle is the presence of "black borders" that commonly appear on the edges of video frames, which may vary in size and location from system to system. The paper demonstrates methods of robustly aligning frames and compositing them so that the limitations just mentioned do not affect the final mosaic quality too severely.
