| Abstract: | Aimed at the problem of object detection of salient motion in video frequency series,a quick detection method of salient motion objects was presented on the basis of their multiple scales and multiple features in the frequency domain of the image.On the basis of multi-scale operation in video sequence and by means of extraction of low-level features from the video sequence,the spatiotemporal phase informations of discrete cosine transform(DCT) were analyzed by using the algorithm presented.Finally,the salie... |
