Abstract(in English) | This paper proposes a computational cost reduction method for moving areaextraction using global motion estimation with KLT tracker and backgroundsubtraction. The proposed method utilizes image shrinking to reduce thecomputational cost. However, the accuracy of estimated global motion mightbe degraded since the number of good feature points for tracking reduces dueto image shrinking. This degraded motion estimation increase the amount ofnoise included in background subtracted images. To alleviate this, theproposed method utilizes median filter on background subtracted binaryimages to reduce noise and also utilizes labeling to remove small regions. For the evaluation of the proposed method, we extract moving areas usingthree video sequences each of which has different camera movement. Inaddition, we analyze the accuracy of the proposed moving area extractionusing F-measure by changing parameters of the proposed method such as thesize of median filter and the threshold area size for small region removal. |
