Abstract : The reliance of many video processing techiniques on motion estimation demands a good motion confidence measure, which is needed to ensure that unreliable estimations are not accepted into a system. This paper proposes a new measure of motion confidence based on phase information from Fourier transform of a video frame. Using the measure, blocks associated with unreliable motion estimation are detected efficiently and accurately. The merit of the technique is a much improved sensitivity over circumstances where other measures show ambiguity. This improvement is demonstrated through our experimental and analytical results.
