| 摘 要： | 为了提高胸部X射线摄影图像中肺结节的正确检测率,提出一种基于通道化Hotelling模型的多尺度匹配滤波算法.以X射线胸片中的正样本和负样本图像作为训练集合,用Hotelling分类器训练出不同尺度的匹配滤波器组,并与待检测的胸片图像做滤波.计算滤波输出图像的视觉检测差异,以最大差异为约束条件寻找最优尺度的滤波器,计算...

| Abstract: | A multi-scale matched filter based on Hotelling classifier is presented to improve the accuracy of nodule detection in chest X-ray radiography.The positive and negative radiography samples are used to train multi-dimension matched filters by Hotelling model.The visual detection difference is calculated using the filter outputs of radiography,and the optimal dimension filter is searched subject to the maximum detection difference.Then the nodule size and detection capability are calculated based on the optim... |
