Automatic lung segmentation in chest radiographs using shadow filter and multilevel thresholding
TL;DR: The results show that the proposed unsupervised lung segmentation method in chest radiographs based on shadow filter and multilevel thresholding is performed accurately and the performance measures are improved from previous work.
Proceedings ArticleDOI
Fall detection using Gaussian mixture model and principle component analysis
TL;DR: The proposed method extracts six postures of physically movements of human including lying, sitting, standing, getting up, walking, and falling from a video camera using a mixture of Gaussian model combined with average filter models.
Proceedings ArticleDOI
Improvement of fall detection using consecutive-frame voting
TL;DR: Improvement of Fall Detection Using Consecutive-frame Voting using a mixture of Gaussian models (MoG) combined with average filter model to implement the subtraction results and results show improvement of the accuracy.

TL;DR: This work presents a method of mapping non-separable input features into a new set of separable features that can be utilized, together with ordinary "uncrossed" features, by a support vector machine (SVM) classifier.
Proceedings ArticleDOI
Exudates detection in fundus image using non-uniform illumination background subtraction
TL;DR: Exudates detection in fundus image using non-uniform illumination background subtraction using level-set evolution without re-initialization is proposed and the experimental results show that the proposed method is robust to non- uniform illumination environment.
