In this paper, we present a novel spatiotemporal salient object detection method to produce high-quality saliency maps. The gradient of optical flow is adopted to coarsely locate the boundaries of salient object and the gray-weighted distance transform is adopted to highlight the whole salient object for a temporal saliency map. Furthermore, a confidence-guided energy function is proposed to adaptively...
We put up forward a high-quality frame interpolation framework and its real-time implementation on heterogeneous computing system. To obtain a truthful optical flow field, the framework takes use of recent progresses in correspondence estimation including randomized search strategy and edge-preserved flow interpolation, and adapts them well into the system through a parallelized design. Firstly, dense...
A novel motion-compensated frame rate up conversion algorithm is proposed in this paper, which employs the iterative non-local means (NLM) interpolation. Firstly, we obtain the forward and backward motion vector fields (MVFs) by optical flow estimation. Then in order to reduce the cracks and salt-and-pepper noise, the initial interpolated frame is reconstructed by the fusion of these two MVFs in block-based...
