Image Segmentation Paper# title: Left ventricle segmentation
Introduction Early diagnosis of CVDs often time-consuming. Need to automate cardiac structure segmentation for image analysis LV Segmentation Challenging problem : LV confused with other MRI regions Expert own experience
Research Objective A ddress LV segmentation in cardiac MRI Build a model locate the ROI segment the LV region Combined CNN and U-Net model
Limitations Inconsistent segmentation boundaries Combined model how it reduces segmentation inaccuracies Insufficient data for model training N ot possible to evaluate model portability.
Conclusion The researchers address the problem of LV segmentation in cardiac MRI. Built a composite model which combines the CNN and U-net. CNN locates the center position of LV crops the ROI from the original MRI U-net completes the segmentation of LV in the ROI
Critical Analysis Segmentation with single or combined CNNs – or modified versions U-Net LV segmentation Localize borders, pixels Touching objects Segmentation mask Fewer training samples
Critical Analysis Combined CNN and U-Net model : accurate LV segmentation . CNN: Locate ROI U-Net: LV segmentation Seg mentation based of viewpoints Semantic segmentation
