 abstract = {Deep neural networks with multilevel connections process input data in complex ways to learn the information. A network’s learning efficiency depends not only on the complex neural network architecture but also on the input training images. Medical image segmentation with deep neural networks for skull stripping or tumor segmentation from magnetic resonance (MR) images enables learning both global and local features of the images. Though medical images are collected in a controlled environment, there may be artifacts or equipment-based variance that cause inherent bias in the input set. In this study, we investigated the correlation between the image quality metrics (IQM) of MR images with the neural network segmentation accuracy. For that we have used the 3D DenseNet architecture and let the network trained on the same input but applying different methodologies to select the training data set based on the IQM values. The difference in the segmentation accuracy between models based on the random training inputs with IQM based training inputs shed light on the role of image quality metrics on segmentation accuracy. By running the image quality metrics to choose the training inputs, further we may tune the learning efficiency of the network and the segmentation accuracy.},
