In this paper, we study the problems of video processing in video search engine. Video has now become a very important kind of data in Internet; while searching for video is still a challenging task due to the inner properties of video: requiring enormous storage space, being independent, expressing information hiddenly. To handle the properties of video more effectively, in this paper, we prop...

Table 1 shows the per video results for the 50 videos from the DAVIS dataset (referred in Table 1 of the main paper). We compare with several semi-supervised and fully automatic baselines. Our method outperforms the per-video best fully automatic and best semi-supervised baseline in 25 out of 50 videos. Table 2 shows the per video results for the 14 videos from the Segtrack-v2 dataset (referred...

With the advent of digital video and digital broadcasting, copyright protection of video data has been one of the most important issues. We present in this paper a novel method of digital watermark for video data based on the discrete wavelet transform. In this method, we embed the watermark in the lowest frequency components of each frame in the uncoded video by using a controlled quantization...

In this letter, we derive an efficient audio/video synchronization method for video telephony. For synchronization, this method does not require any further RTCP packet processing except for the first one. The derived decision rule is far more compact than the conventional method. This decision rule is incorporated in an actual video telephony system adopting Texas Instruments (TI) OMAP 1510 pr...

We present a method for generating a 3D feature flow field from a video and its application to video stylization. Our method extracts smoothly aligned 3D vectors that describe the smallest variation of colors in both spatial and temporal dimensions of the video, and thus efficiently preserves both spatial and temporal coherence in a relatively inexpensive manner. We use this flow field forms th...

In this paper we propose a novel feature extracting method based on spatiotemporal slice analyzing. To date, video features are focused on the character of every single video frame. With our method, the video content is no longer represented with every single frame. The temporal variation of visual information is taken as an important feature of video in our method. We examined this kind of fea...
