This paper reports the recent inter-layer filtering development for the scalable extension of the high-efficiency video coding (HEVC). The essential difference between scalable and single-layer video coding technology is the existence of the inter-layer redundancy, which can be exploited by the interlayer prediction to improve the coding efficiency. One form of inter-layer prediction is to up-sample...
In this paper we deal with the problem of power line detection from millimeter-wave radar video. We propose an algorithm that is based on Hough Transform, Support Vector Machine, and particle filter tracking. We explore the defining characteristics of the power lines in the radar video, and present an approach to utilize these characteristics together with the temporal correlation property of the...
Power-line-strike accident is a major safety threat for low-flying aircrafts such as helicopters, thus an automatic warning system to power lines is highly desirable. In this paper we propose an algorithm for detecting power lines from radar videos from an active millimeter-wave sensor. Hough Transform is employed to detect candidate lines. The major challenge is that the radar videos are very noisy...
We present a new error concealment algorithm for spatially scalable video coding with frame loss in the enhancement layer, based on the technique of hallucination. For a lost enhancement layer frame, the error concealment is done as hallucinating its base layer frame, using the database trained from previously decoded frames nearby to the lost one. Simulation results show that the proposed method...
We propose a new error concealment method based on hallucination for Scalable Video Coding with spatial scalability. In this method, parts of the frames which lose the enhancement layer are up-sampled from base layer and ldquohallucinatedrdquo as concealment frames. The database for hallucination is generated from the high-resolution and low-resolution frame-pairs near the lost frames in the video...
