Joint analysis of medical data collected from different imaging modalities has become a common clinical practice. Therefore, image fusion techniques, which provide an efficient way of combining and enhancing information, have drawn increasing attention from the medical community. In this paper, we propose a novel cross-scale fusion rule for multiscale-decomposition-based fusion of volumetric medical...
We propose a mathematical model for optimizing pixel aspect ratio for the best 3D estimation in both stereo-based 3D reconstruction and 3D viewing applications. We analyze the 3D reconstruction through a 3D display medium and reduce the whole process to a single stereo system so that a unified model can be applied to both direct reconstruction from stereo images and indirect reconstruction through...
Fluid vector flow (FVF) is a recently developed edge-based parametric active contour model for segmentation. By keeping its merits of large capture range and ability to handle acute concave shapes, we improved the model from two aspects: edge leakage and control point selection. Experimental results of cavity segmentation in chest radiographs show that the proposed method provides at least 8% improvement...
