In allusion to P-M do not take the directional construction of local image into consideration, and to solve the false edge caused by using Weickert diffusion tensor to process the flat part of the image. A MR image de-noising algorithm based on improved Weickert diffusion tensor model has been proposed in this paper, by using continuous threshold, selecting appropriate eigenvalue modification method...
In this paper, we propose a novel image retrieval method called hybrid information descriptors (HIDs) consisting of mutual information descriptors (MIDs) and self information descriptors (SIDs). Based on the physiological structure of human eyes and visual perception mechanism, HIDs are designed to explore the internal correlations among different image feature spaces with image structure and multi-scale...
Despite the efforts to reduce the so-called semantic gap between the user's perception of image similarity and the feature-based representation of images, the interaction with the user remains fundamental to improve performances of content-based image retrieval (CBIR) systems. It is fact that the effectiveness of a CBIR system strongly depends on the set of visual features and the ‘metric’ used to...
