The heart is a vital human organ that sometimes has dangerous abnormal conditions, such as: atrioventricular septal defect (AVSD), atrial septal defect (ASD), and ventricular septal defect (VSD). In this final project, we propose a Faster R-CNN architecture method using several backbones such as VGG16, Resnet50 and mobilenetv1 as heart detectors. The dataset used is a dataset in the form of an …
