FERNSEH-SIGNAL-BEARBEITUNG |
摘要 |
Cuts in a video signal are detected by first measuring a correlation parameter between successive images; this can be the sum of the maximum peak heights for each of 16 to 100 or more blocks in a block-based phase correlation procedure. An averaged value of this correlation parameter is maintained and the current measurement of the correlation parameter is compared with the averaged value. The presence of a cut is inferred where the current measurement drops beneath, say, 50% of the average value. |
