Abstract�� To resolve the video compression bit rate fluctuation due to odd frames generated by the bad weather or electromagnetic (EM) interference in aerial video sequences from unmanned aerial vehicle (UAV), a new video compression method which analyze video sequences in advance and remove the detected odd frames before video compression was proposed. By constructing models of several popular types of odd frames, the characters of odd frame signals were analyzed. With combination of signal statistics and information entropy measurements, the odd frames in video sequence were robustly detected. Finally, the video sequence without odd frames was compressed with the new H.264 standard. Both theoretic analyses and experiments prove that this method greatly improves video compression efficiency of aerial video sequences from UAV and keeps constant compression bit rate, meanwhile does not lose any useful information.
