Automatic image annotation is a challenging problem in multimedia content analysis and computer vision. In this paper, we propose a hierarchical framework for multi-label image annotation. We first present an image-filtering algorithm to remove most of the irrelevant images for an unlabeled image. In the image-filtering algorithm, an image cluster is allocated using a discriminative model as the primary...
Computationally detecting salient image object based on human attention is of great significance for image understanding. In this paper, we introduce a method for saliency map generation with a novel way of extracting texture feature and a strategy for feature fusion. Our method combines texture and color region contrasts to make the salient object stand out from images. We compare our algorithm to...
Many digital beamforming algorithms result in a set of complex weights including amplitudes and phases. The use of complex weights offers greater control over the array response at the expense of system complexity. And these approaches typically assume a wide sense stationary environment and utilize auxiliary training data to estimate the statistics of the interference. However, for a dynamic environment...
