We present a method to automatically estimate and remove the bias field of MR images where there is a single dominant tissue class. Assuming that a multi-class image is corrupted by a multiplicative, low-frequency bias field, the method evaluates the bia
MRI acquisition parameters from patien t to patien t and from slice to slice. Therefore, the correction of in tensit y inhomo- geneities is usually required for eac h new image. In the last decade, a n um b er of algorithms ha v e b een prop osed for the in tensit y inhomoge...
摘要,图像中存在的灰度不均匀现象与演化曲线被错误的目标边缘引导给图像的多相分割带来了很大困难。针对这一问题,利用对数变换将乘性偏移场转化成线性偏移场,通过核函数引入局部灰度信息建立了偏移场矫正模型。此外,运用水平集函数与图像梯度的方向信息重建了边缘指示函数,增强了演化曲线对正确目标边缘的识别能力。人工合成...
The DC strategy focuses on identifying the aspects of the climate model that need correction (in our case the long-term mean), and then uses the observations to find a correction factor for the quantities of interest (e.g. long-term average monthly mean temperature). To illustrate the method...
For 4/28 participants in the rPPC cTBS cohort, MRI scans could not be obtained due to logistical challenges. For these participants, the distance between the right and left tragus, and the inion and nasion were measured, and the scan of the participant with the most similar head ...
