چکیده
This article studies remote sensing image retrieval using kernel-based support vector data description (SVDD). We exploit deep SVDD, which is a well-known method for one-class classification to recover the most relevant samples from archive. To this end, neural network (DNN) jointly trained map into hypersphere of minimum volume in latent space. It expected that similar query are compressed inside hypersphere. The closest embedding center related sample query. enhance SVDD by injecting statistical information DNN means additional terms cost function. first enhancement takes advantage covariance regularization batches training set penalize unnecessary redundancy and minimize correlation between different dimensions embedding. second involves unlocking hypersphere's predefined while preventing divergence during training. Therefore, two parameters designed control importance drifting fixed (convergence), respectively. has been implemented considering average each iteration as updated center. pushes irrelevant away samples, making clustering easier DNN. performance proposed methods evaluated on benchmark datasets.

متن کاملAdaptive Single Image Superresolution Approach Using Support Vector Data Description
An adaptive single image superresolution (SR) method using a support vector data description (SVDD) is presented. The proposed method represents the prior on high-resolution (HR) images by hyperspheres of the SVDD obtained from training examples and reconstructs HR images from low-resolution (LR) observations based on the following schemes. First, in order to perform accurate reconstruction of ...
