We introduce a Multiple Granularity Analysis framework for video segmentation in a coarse-to-fine manner. We cast video segmentation as a spatio-temporal superpixel labeling problem. Benefited from the bounding volume provided by off-the-shelf object trackers, we estimate the foreground/ background super-pixel labeling using the spatiotemporal multiple instance learning algorithm to obtain coarse...
This paper proposes a method of invasion detection on transmission lines using saliency computation. Previous researches mainly extract transmission lines with Canny edge detector and Hough transformation (HT), then detect invasions from the topological characteristics along the lines. However, HT works poorly in the system where transmission lines are curves, and too many false detection will arise...
The general configuration of body is a valuable cue for human identification, which is ignored by the existing approaches. In this paper, we present an approach for human identification by using body prior and the generalized Earth Mover's Distance (EMD). The common knowledge that a pedestrian is composed of upper body and the lower one is employed as a body prior. To achieve more robust body segmentation,...
We explore the principles of quaternion wavelet construction for achieving multiscale analysis of geometric image features. Then the quaternion wavelets are applied to propose a cooperative stereo matching algorithm using top-down segmentation-based disparity propagation. Without bidirectional matching to remove ambiguous outliers, uniqueness constraint is enforced on cost function by inhibiting the...
In this article, we present a detailed theoretical analysis and a prototype implementation of a family of cameras designed with the explicit goal of detecting and removing interfering dynamic occluders in real time, during live capture, as opposed to fixing the resulting artifacts a posteriori. Such an early-acquisition approach improves efficiency: more valid samples are acquired faster without worrying...
In this paper, we propose a novel method of motion segmentation through image sequence. In our work, no assumptions of boundary densities, color, or textures are made about the background or the object. Neither do we assume any special motion model to the background or the object. With the help of classic Bayesian theory, an energy function describing the piece-wise smooth motion field of the image...
