Performance on Bladder
The DIRNet 4 network, trained with more Conv layers, showed a better performance with respect to the basic DIRNet model in terms of the Dice, ASSD, and Jaccard indices. This indicates that adding more Conv layers would significantly improve the performance of the model for all three organs. Furthermore, the basic DIRNet and DIRNet 4 models exhibited improved performance in image registration for the bladder. However, the remaining models failed to improve bladder deformation.
