SAR (Synthetic aperture radar) has the advantages that it can be observed all day long and all weather. Space borne SAR is able to observe the target area periodically, therefore the extraction of lakes using SAR image is more and more widely used. The detection and update of lake plays an important role in water resources managing, water environment monitoring and watershed management. The traditional...
In this paper, we present a superpixel segmentation algorithm called linear spectral clustering (LSC), which is capable of producing superpixels with both high boundary adherence and visual compactness for natural images with low computational costs. In LSC, a normalized cuts-based formulation of image segmentation is adopted using a distance metric that measures both the color similarity and the...
Traditional automatic face recognition methods focus on handling frontal or near frontal face images. Therefore, they cannot be directly applied to the pose-varied or non-frontal face images captured by non-intrusive video surveillance systems. In this paper, a non-frontal face recognition algorithm based on elastic bunch graph matching (EBGM) is proposed. The proposed method measures face similarity...
