5-1 動画圧縮による顔検出誤差についての検討(第5部門 メディア処理2)

抄録

We investigate how video compression artifacts affect face detection performance. VP6-encoding yields a gradual fall of the recall ratio as the bit-rate is reduced, especially for small faces. Recall and precision also fluctuate with bit-rate, implying interaction between sizes of block noise and rectangle features used by the face detector.
