We combine in this paper the topological gradient, which is a powerful method for edge detection in image processing, and a variant of the minimal path method in order to find connected contours. The topological gradient provides a more glo...

Multiple sclerosis (MS) is a complicated disease characterized by heterogeneous pathology that varies across individuals. Accurate identification and quantification of pathological changes may facilitate a better understanding of disease pa...
Modulating the focus of attention for spoken words at encoding affects frontoparietal activation for incidental verbal memory [0.03%]
语音词的眼动焦点变化对前顶叶偶然性言语记忆激活的影响

Thomas A Christensen et al.
Attention is crucial for encoding information into memory, and current dual-process models seek to explain the roles of attention in both recollection memory and incidental-perceptual memory processes. The present study combined an incident...

Aim. To develop a new invariant descriptor for the characterization of protein surfaces, suitable for various analysis tasks, such as protein functional classification, and search and retrieval of protein surfaces over a large database. Met...
A finite element mesh aggregating approach to multiple-source reconstruction in bioluminescence tomography [0.03%]
一种新的二维生物发光断层成像多源同时重建方法
Jingjing Yu,Fang Liu,L C Jiao et al.
Jingjing Yu et al.
A finite element mesh aggregating approach is presented to reconstruct images of multiple internal bioluminescence sources. Rather than assuming independence between mesh nodes, the proposed reconstruction strategy exploits spatial structur...
A bayesian hyperparameter inference for radon-transformed image reconstruction [0.03%]

We develop a hyperparameter inference method for image reconstruction from Radon transform which often appears in the computed tomography, in the manner of Bayesian inference. Hyperparameters are often introduced in Bayesian inference to co...
Segmentation of juxtapleural pulmonary nodules using a robust surface estimate [0.03%]
基于稳健表面估计的肺相邻血管结构分割算法研究
Artit C Jirapatnakul,Yury D Mulman,Anthony P Reeves et al.
Artit C Jirapatnakul et al.
An algorithm was developed to segment solid pulmonary nodules attached to the chest wall in computed tomography scans. The pleural surface was estimated and used to segment the nodule from the chest wall. To estimate the surface, a robust a...
Conditional random fields and supervised learning in automated skin lesion diagnosis [0.03%]
条件随机场和监督学习在皮肤病变自动诊断中的应用
Paul Wighton,Tim K Lee,Greg Mori et al.
Paul Wighton et al.
Many subproblems in automated skin lesion diagnosis (ASLD) can be unified under a single generalization of assigning a label, from an predefined set, to each pixel in an image. We first formalize this generalization and then present two pro...
Fast random permutation tests enable objective evaluation of methods for single-subject FMRI analysis [0.03%]
快速的随机置换检验使得单被试fMRI分析方法的客观评估成为可能
