Five DNNs were trained with a brain image series (preprocessed in five different ways), to judge the age-range of a volunteer. The performance of the DNNs was then compared statistically. The results suggested that image preprocessing may facilitate higher accuracy, and also make it easier to understand how and why a judgement was made., ISMRM 2016 2016 Annual Meeting}, title = {Deep-Neural-Network based image diagnosis: comparing various image preprocessing}, year = {2017} }
