In practice, such a problem is often encountered that the proportion of target to background in image segmentation is very small. For this, a thresholding method used for the image segmentation of infrared small target is proposed in this paper, which is based on the area difference between background and target and intra-cluster variance. This method points out the existing methods of image threshold...
In this paper, we present an unsupervised classification algorithm for hyperspectral images. For reducing the dimension of hyperspectral data, we use a linear unmixing algorithm to extract the endmembers and their abundance maps. Compared to the components obtained by traditional PCA-based method, the abundance maps have physical meanings (such as the abundance of vegetation). For determining the...
Image based rendering is a promising way to produce arbitrary views of a scene using images instead of object models. However, depth variations and occlusions cause blurring in the rendered images. The solution is to use some geometrical information in order to steer the interpolation filters according to the depth. The level of detail of this geometry is often predetermined. In this paper, we present...
