Influence of altering the loss objective during cGAN training on the segmentation performance of the medial gastrocnemius and vastus muscles.

The cGAN was trained with a ${\mathcal{L}}_{\text{c}\text{G}\text{A}\text{N}}+\text{λ}{\mathcal{L}}_{\text{L}2}$ loss objective for 50 epochs followed by a further 50 epochs training with ${\mathcal{L}}_{\text{c}\text{G}\text{A}\text{N}}+\text{λ}{\mathcal{L}}_{\text{L}1}$.

Abbreviations: VMM - vastus medialis muscle, GMM – medial head of gastrocnemius muscle, DSC – Dice Similarity Coefficient
